Women in Science Lecture
Presented By Professor Nicola Morley, Professor of Materials Physics, University of Sheffield
About this event
Prof Nicola Morley is a Professor of Materials Physics and currently a Royal Society Leverhulme Trust Senior Research Fellow within the Department of Materials Science and Engineering at the University of Sheffield. Her main research is on functional magnetic materials, investigating how the fabrication processes influence the structural and functional properties, then using this knowledge to develop new materials for applications. Her research highlights include the development of highly magnetostrictive Fe-based thin films for sensors and electric-field controllable ferroelectric/ferromagnetic structures, along with the exploration of functional high entropy alloy films as the next big thing in soft magnetic materials. Also using novel process techniques (SPS, ALM) to produce magnetocaloric materials for commercial applications and developing magnetostrictive actuators and sensors for structural health monitoring of aerospace components.
Prof Morley will deliver two talks, one on research and the other on her career:
- Talk 1: 12.15-12.55-Functional Magnetic Materials
Abstract: Functional Magnetic thin films are found a wide range of applications from data storage (computer hard drives) to strain and field sensors. My research aims to understand how the fabrication parameters change the structural and magnetic properties of magnetic films, allowing tuning of these properties for applications. The research has focused on thin Fe-based films grown by sputtering, and how changing the parameters (power, pressure, applied field) changes the structure/morphology of the films and the magnetic properties (coercive field, saturation magnetisation and magnetostriction constant). Recent research has focused on the addition of up to 3 elements of roughly equimolar into FeCo, to form high entropy alloys, which is an exciting new research area. It has been found that Cr causes the films to become amorphous with a small coercive field, while Al increases the magnetostriction constant. When NiCrAl is added to FeCo, very soft magnetic films are produced, which are competitive with existing magnetic films.
