Rare earth iron garnets (RIG) are drawing great interest in recent years due to their excellent performance in the field of spintronics because of the low Gilbert damping and long spin diffusion length. RIG/normal metal heterostructures have been widely used to study Spin Hall magnetoresistance, spin seebeck effect phenomena which are mainly induced by a spin current through the interface. One of the more attractive possibilities effect is the current induced control of magnetization in perpendicular magnetic anisotropy (PMA) RIG by spin orbit torque (SOT). Here we present the successful growth of thulium iron garnet (TmIG) and gadolinium iron garnet (GIG) by pulsed laser deposition. PMA is induced by lattice strain between films and substrate. The obtained PMA garnet films show low coercivity (< 5 mT) with thickness under 10 nm, which will benefit the study of magnetic moment switching with low current density.
