Magnetic study of the terbium iron garnet, Tbig, along the easy (111) direction : molecular field parameters

Magnetization and susceptibility measurements, over the range 4.2-295 K have been made on single crystal TbIG along the (111) direction. The paramagnetic Curie point and the Curie constant are markedly different from the values established by Pauthenet in polycrystalline samples. The effects of the crystalline field are found to be important over all the temperature range studied. From the experimental results, we deduce molecular fields parameters representing the magnetic interactions on the rare earth sublattice.
