A procedure to extract the magnetocaloric parameters of the single phases from experimental data of a multiphase system.
Description
In this work, we propose a method to extract the individual parameters that describe the field
dependence of magnetic entropy change of each phase in a multiphase system. This method makes
use of the scaling laws of the magnetocaloric effect and can help us to determine the behavior of
individual phases and to predict their critical exponents. The accuracy of the procedure is
illustrated applying it to ball milled powders, in which an amorphous phase with
T
C
around room
temperature coexists with bcc-Fe type crystallites. The obtained values are in good agreement with
those reported in the literature for single phase systems. The proposed method could be applied to
other systems where single phase materials cannot be easily obtained in order to characterize the
effect of impurities.
