Cortie, David

Overview

I am a condensed matter physicist working on topological electronic materials and magnetic materials. My speciality is measuring the atomic-scale structure and excitations of materials using neutron scattering. Neutrons, as an example of a quantum beam, offer a unique perspective on the universe as they interact via nuclear forces, yielding different contrast from "common" X-rays and electrons. I use polarised neutron reflectometry to study thin-film magnets, and neutron spectroscopy to reveal magnonic and phononic features. I hold a fractional appointment at UoW, and the remainder of my time is spent as a scientist at the Australian Nuclear Science and Technology Organisation, where I am now co-responsible for the PLATYPUS neutron reflectometer.

Research Overview

I am a senior research fellow at the Institute for Superconducting and Electronic Materials within AIIM. I am also a guest lecturer within School of Physics, EIS. I am an honorary Associate Investigator in the national ARC Centre for Excellence in Future Low Energy Electronics Technologies.

My research is focused on the electronic and magnetic properties of solid-state materials in the form of single crystals and thin films.

I study the structure-function relationship in novel compounds with applications in spintronics and thermoelectricity. Neutron reflectometry and diffraction, in tandem with electron microscopy, are used to reveal atomic-scale details. Neutron spectroscopy provides insights into the way that heat and magnetic information is transmitted via phonons and magnons in new materials.

Keywords: nanomagnetism, spintronics, strong-correlated electron systems, oxide materials, neutron spectroscopy, density functional theory, diffraction, crystallography, polarised neutron reflectometry, topological materials, electron microscopy, X-ray diffraction, magnetometry, magnetotransport, thermal conductivity
