Light Induced Magnetisation Switching in Inversion Breaking Magnetic Materials — •Urmimala Dey1,2, Oles Matsyshyn1, and Inti Sodemann11Max Planck Institute for the Physics of Complex Systems, Dresden 01187, Germany — 2Indian Institute of Technology Kharagpur, Kharagpur 721302, India

We consider the effect of non-linear optical and transport electronic processes on the magnetisation dynamics in materials that break both inversion and time reversal symmetry, with particular focus on the interplay of Berry phases and non-linear processes such as the non-linear Hall effect and the shift and injection currents. In particular we describe an injection current process that is allowed when both of these symmetries are broken and that could facilitate optical control of magnetisation switching processes even with linearly polarised light. We will comment on potential material platforms to experimentally detect these effects.
