Half-metallic ferromagnets

York Warwick team

This is the home page for a new collaborative project to study thin film half-metallic ferromagnetic (HMF) materials. An ideal HMF has 100% spin polarisation at the Fermi level, i.e. for one electron spin channel it is a semiconductor while the other spin channel behaves like a metal. However, real HMFs in the form needed for spintronic devices are far from ideal! We are studying 3 classes of HMF material in thin-film form, aiming to understand and fix the sources of the non-ideal HMF behaviour. Increasing the effective spin polarisation at room temperature will help us to improve the performance of spintronic devices, which could form the basis of a new generation of low-energy data storage and processing components.

Our work is supported by EPSRC via the project Half-metallic ferromagnets: materials fundamentals for next-generation spintronics. The collaboration is principally between the Physics Departments of Warwick and York Universities, with partners including Toshiba Research Europe Ltd., Diamond Light Source and Synchrotron Soleil.
