Magnetization dynamics of the compensated ferrimagnet \(Mn_{2}Ru_{x}Ga\)

Here we study both static and time-resolved dynamic magnetic properties of the compensated ferrimagnet from room temperature down to 10K, thus crossing the magnetic compensation temperature \(T_{M}\). The behaviour is analysed with a model of a simple collinear ferrimagnet with uniaxial anisotropy a...

Description
Summary:Here we study both static and time-resolved dynamic magnetic properties of the compensated ferrimagnet from room temperature down to 10K, thus crossing the magnetic compensation temperature \(T_{M}\). The behaviour is analysed with a model of a simple collinear ferrimagnet with uniaxial anisotropy and site-specific gyromagnetic ratios. We find a maximum zero-applied-field resonance frequency of \(\sim\)160GHz and a low intrinsic Gilbert damping $\alpha$$\sim$0.02, making it a very attractive candidate for various spintronic applications.
