Abstract

Magnetization curves ⟨S z ⟩(B, T) for magnetic impurities which couple to the host medium via exchange interactions are computed using the numerical renormalization group. Deviations from the ideal paramagnetic behavior (as described by the Brillouin function) is discussed for various TT K ratios, where T K is theKondo temperature, focusing on the implications for the interpretation of experimental X-ray magnetic circular dichroism (XMCD) results. The case of anisotropic impurities is also considered.
