Physics of Superconductivity and Magnetism

We report the experimental observation, with pulsed field, of the anisotropy in magnetization theoretically predicted for single crystals of TmSb. Agreement with crystal-field-only theory is excellent at 1.5°K. At 20.4°K, agreement between isothermal theory and experiment is poorer. This discrepancy can be explained if spin-lattice relaxation effects cause the observed magnetization to be a mixture of isothermal and adiabatic effects.
