| contents | Ferromagnetic insulating garnet films with perpendicular magnetic anisotropy (PMA) are of great importance for the applications in spintronics. Tm3Fe5O12 (TmIG) with magnetoelastic anisotropy has been proven to exhibit PMA more easily than Y3Fe5O12. Here, magnetic parameters of TmIG films with various thicknesses are investigated by ferromagnetic resonance. The relationship between effective magnetic magnetization, surface perpendicular anisotropy field, magnetic anisotropy constants and film thickness is established. The parameters of spin Hall angle, spin diffusion length, and real part of the spin mixing conductance are obtained from the measurements of angular dependent magnetoresistance of TmIG/Pt heterostructures. |
