Two-step-like magnetization curves of YR(CoAl) 2, R=Ho, Er, in fields up to 100 T
Abstract
The magnetization curves of the compounds Y 0.8Ho 0.2(Co 0.925Al 0.075) 2 and Y 0.83Er 0.17(Co 0.92Al 0.08) 2 have been measured in fields up to 100 T. Two metamagnetic transitions connected with magnetic instability of the d-subsystem have been observed for both compounds. Their numerical analysis within the molecular-field theory enables a precise determination of the f-d exchange parameters.
