The magnetocrystalline anisotropy of the pseudobinary (Pr1-xNdx)2Fe14B compounds has been measured by using the singular point detection (SPD) technique.

Abstract
The magnetocrystalline anisotropy of the pseudobinary (Pr1-xNdx)2Fe14B compounds has been measured by using the singular point detection (SPD) technique. The measured temperature and composition dependence of the anisotropy field has been compared with the data obtained in CEF approximations using different sets of (Anm) parameters for Nd2Fe14B and Pr2Fe14B and by considering a linear combination of the anisotropy in the mixed system. The comparison is made by calculating the anisotropy constants, then the anisotropy field values, starting from the (Anm) parameters. Experimental and calculated data concerning the occurrence of spin reorientation transition (SRT) and of type 1 and type 2 first-order magnetisation processes (FOMP) as a function of composition have also been compared.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
