Magnetization dynamics of the compensated ferrimagnet Mn2RuxGa

Here we study both static and time-resolved dynamic magnetic properties of the compensated ferrimagnet Mn2RuxGa from room temperature down to 10 K, thus crossing the magnetic compensation temperature TM. The behavior is analyzed with a model of a simple collinear ferrimagnet with uniaxial anisotropy...

Description
Summary:Here we study both static and time-resolved dynamic magnetic properties of the compensated ferrimagnet Mn2RuxGa from room temperature down to 10 K, thus crossing the magnetic compensation temperature TM. The behavior is analyzed 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 ∼160GHz and a low intrinsic Gilbert damping α∼0.02, making it a very attractive candidate for various spintronic applications.
