Current Research Interests

Paul has interests mainly in studying magnetic materials with magnetic reflectivity and diffraction. He has helped to establish a deeper understanding of X-ray reflectivity during magnetic hysteresis highlighting the importance of non-linear dependence on the magnetic moment. He also has an interest in the influence of current and voltage on the magnetic states of materials. Part of this interest lies  in multiferroics and currently shares a student looking at the role of the spin ordering on the multiferroic properties of M type hexaferrites. The other part involves the role of spin orbit torque in thin films where the application of currents has been proven to switch the direction of the magnetic state of thin ferromagnetic films.


With scientists from the University of Leeds and ISIS we are examining the magnetic fluctuations in frustrated systems. Frustration arises when nearest neighbour interactions cannot be fulfilled due to the crystal structure. These materials do not obey the third law of thermodynamics since there can be many ground states at zero kelvin. By growing artificial systems we have been able to look at the interactions between islands over periods of several hours at different temperatures.

Paul Steadman started his career looking at the growth and structure of magnetic thin films of Cr and Fe using surface X-ray diffraction. During his first postdoctoral position he extended his experience into measuring the induced magnetism at Pt surfaces and Pt thin films using resonant scattering. He also designed, built and tested a system for measuring the magneto-optical Kerr effect (MOKE) on the surface diffraction end station. At the university of Leeds he went on to studying exchange bias and the role of disorder in thin films using soft X-ray and neutron reflectivity. At Diamond Light Source he helped to build the nanoscience (I06) beamline with Sarnjeet Dhesi. This was the first beamline to receive users. Later on he went on to lead the design and build of the BLADE (I10) beamline which he currently runs.
