COMPARISON OF CONVENTIONAL AND SPARK PLASMA SINTERING ROUTES FOR THE FABRICATION OF ROOM TEMPERATURE MAGNETOCALORIC MN-FE-P-SI

摘要

We report on the structural and magnetic characterization of Mn-Fe-P-Si room temperature magnetocaloric compounds. The samples are prepared by different routes: powder annealing, conventional and spark plasma sintering. The effect of preparation route on the magnetic and structural properties is investigated.
