Ferrimagnetic materials are interesting candidates for future spintronics applications due to high frequency dynamics and low net magnetic moment. In my talk, I will present my research on perpendicularly magnetized ferrimagnetic Tb/Co multilayer systems grown on Pt. This heterostructure allows efficient manipulation of ferrimagnetic domains through spin-orbit torques induced by the heavy metal Pt. The latter firstly allows the generation of spin currents from charge currents and secondly breaks the system symmetry by introducing a non-collinear exchange interaction at the Pt/ferrimagnet interface. I will show how the stacking order of the Tb/Co layers dramatically changes the magnetization compensation temperature and how the layer thicknesses result in a different efficiency of the spin-orbit torques.
