Abbundi, R; Clark, A E

The magnetization and magnetostriction of single-crystal TmFe/sub 2/ were measured as a function of temperature from 4K to 300K. TmFe/sub 2/, 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 erg/cc at room temperature to the extrapolated value of 15 x 10/sup 8/ erg/cc at 0 K. The saturated magnetic moment was found to be 74 emu/g, which is substantially larger than previous polycrystalline results. The temperature dependence of the magnetostriction closely follows single-ion magnetoelastic theory.
