Prof Julia Staunton (Warwick): Extending Density Functional Theory (DFT) to finite temperatures to describe spintronics, refrigeration and permanent magnetic effects
Physical Sciences colloquia

The DFT-based Disordered Local Moment Theory of magnetic materials and its quantitative description of the temperature and field dependence of magnetic phase transitions will be discussed [1,2]. The intricate interplay between itinerant and more localised spin degrees of freedom leads to temperature dependent spin-polarised electronic structure and transport properties. How caloric effects for refrigeration can be estimated will be explained [3] and results for the magnetic properties of rare earth - transition metal magnets such as SmCo5 presented [4].
