Magnetism is well known as a source of fundamental unsolved problems in material physics and condensed matter. It is also an area famous for practical application: the ability to record and read information from magnetic materials is the basis of nearly all mass data storage devices. The aim of this project is to provide first measures of certain key energies and rates associated with magnetic processes. Through a combination of theoretical modelling and experiment design, a new experimental technique will be developed into a powerful analysis tool. This work will establish the technique in Australia and create new opportunities for future study.

Theoretical and experimental studies of exchange bias in thin films. Films containing layers of different types of magnetic materials - in particular, ferromagnetic and antiferromagnetic - have properties which are being exploited in magneto-electronic devices used in recording and manipulation of computer data. These properties are determined by new types of magnetisation processes in the interface between layers.

Films containing layers of different types of magnetic materials - in particular, ferromagnetic and antiferromagnetic - have properties which are being exploited in magneto-electronic devices used in recording and manipulation of computer data. These properties are determined by new types of magnetisation processes in the interface between layers. In this project investigations of the magnetic behaviour of interfaces will be made to provide information of value in the design and optimisation of new and existing devices. The procedures to be developed in this project will be applicable to the understanding of the behaviour of a new range of atomically engineered magnetic structures.Read moreRead less

Meta-microscopy of insect tissue: How nature grows bicontinuous nanosolids. Several butterfly species grow a complex nano-sculptured matrix whose chiral network structure confers remarkable optical properties, including jewel-like reflections. The formation process remains mysterious and a spectacular case of bottom-up self-assembly at far larger scales than accessible in the lab. The project aims to decipher this process, by (a) tomography of a species where arrested growth sites represent time ....Meta-microscopy of insect tissue: How nature grows bicontinuous nanosolids. Several butterfly species grow a complex nano-sculptured matrix whose chiral network structure confers remarkable optical properties, including jewel-like reflections. The formation process remains mysterious and a spectacular case of bottom-up self-assembly at far larger scales than accessible in the lab. The project aims to decipher this process, by (a) tomography of a species where arrested growth sites represent time-frozen snapshots of the development, and (b) by a combination of micron-resolved in-vivo microscopy of a developing butterfly wing with a growth model to infer nanometer-scale information. This insight will lead to blueprints for self-assembly strategies and shed light on function and form of inner-cellular membranes. Read moreRead less
Environmentally responsive clean coatings. Nature makes use of a range of fascinating surface properties, such as the leaves of the Lotus plant which stay clean even in dirty environments. In this project we will explore the molecular properties of novel polymer coated surfaces that-similar to some natural surfaces-can adapt to changing environmental stimuli and be resistant to contamination. Specifically, we aim to develop self-cleaning polymer coatings which can reversibly switch from wettab ....Environmentally responsive clean coatings. Nature makes use of a range of fascinating surface properties, such as the leaves of the Lotus plant which stay clean even in dirty environments. In this project we will explore the molecular properties of novel polymer coated surfaces that-similar to some natural surfaces-can adapt to changing environmental stimuli and be resistant to contamination. Specifically, we aim to develop self-cleaning polymer coatings which can reversibly switch from wettable to non-wettable with changing temperature and humidity. These self-cleaning polymer surfaces with environmentally responsive properties will add value to pre-painted steel products and other coatings.Read moreRead less

Summary
Magnetic biosensing: developing high frequency spintronic sensors for magnetic label detection. This project builds upon recent advances in nano-magnetism to develop novel, miniaturised, electronic biosensors. Such biosensors will one day enable the production of portable devices for rapid, on-site detection of cancer and other diseases, thereby reducing reliance on costly laboratory based analyses and improving remote and rural healthcare.
Nanoscale quantum metrology using circuit quantum electrodynamics. Using superconducting microcircuits, we aim to control microwave photons in order to achieve detection of nanoscale electrical and mechanical systems that is limited only by the constraints imposed by quantum mechanics. Such quantum-limited measurements will enable the use of quantum feedback for enhanced control of these nanoscale devices.

Imaging defects at atomic resolution via state-of-the-art atomic force microscopy and petascale simulations. Atomic force microscopy (AFM) promises to deliver resolution of individual atoms on surfaces and therefore, in principle, is capable of observing surface defects. However, the image obtained is a convolution of many complex interactions. Thus the key questions are what is being actually observed when we see something with “atomic resolution” in AFM and can point defects be really detected ....Imaging defects at atomic resolution via state-of-the-art atomic force microscopy and petascale simulations. Atomic force microscopy (AFM) promises to deliver resolution of individual atoms on surfaces and therefore, in principle, is capable of observing surface defects. However, the image obtained is a convolution of many complex interactions. Thus the key questions are what is being actually observed when we see something with “atomic resolution” in AFM and can point defects be really detected? The aim of this proposal is to combine state-of-the-art experimental AFM techniques with computer simulations that are capable of generating AFM images to answer these questions. Our ability to harness the potential of AFM for many applications in areas such as nanoscience and crystal engineering hinges on being able to correctly interpret AFM images.Read moreRead less
