Abstract:

The magnetization and magnetostriction of single crystal TmFe2 were measured as a function of temperature from 4K to 300K. TmFe2, because of its highly anisotropic 4f charge distribution, displays a huge magnetocrystalline anisotropy and magnetostriction at cryogenic temperatures. The anisotropy spans the range from -530000 ergcc at room temperature to the extrapolated value of 15 x 10 to the 8th power ergcc at 0 K. The saturated magnetic moment was found to be 74 emug, which is substantially larger than previous polycrystalline results. The temperature dependence of the magnetostriction closely follows single-ion magnetoelastic theory.
