Description
Magnetic AC susceptibility (χAC) has been measured as a function of the temperature and the excitation frequency (ω) in order to study the nature of the Co 3d magnetic moment in the paramagnetic phase of ErCo2. The χAC measurements show a small feature near 100K, both as a function of ω and temperature, associated with a relaxation process of intrinsic Co moments. The calculated Co magnetic moment from those measurements is around 0.20μB. This result has been confirmed by means of X-ray magnetic circular dichroism measurements above and below the magnetic transition of ErCo2, yielding to an intrinsic Co moment of 0.19μB in paramagnetic phase
