MEASUREMENTS AND SCALING ANALYSIS OF POWER LOSSES IN La-CONTAINING ALLOYS

Roman Gozdur – Mariusz Najgebauer

   The paper presents the measurements and the scaling analysis of power losses in the La-containing magnetocaloric material. Power losses in the bulk LaFe10.8Co1.1Si1.1 sample were measured as a function of maximum magnetic polarization Jm and frequency f of magnetizing field. The temperature influence on power losses was revealed. The power losses were also a subject of the scaling analysis, what allowed determining the temperature dependencies of the scaling exponents α and β.

Keywords: La-containing magnetocaloric materials, power losses measurements, scaling analysis, scaling exponents
