Experimental Study of Magnetic Materials Obtained via Fusing with Laser Radiation

The article presents the results of studying the magnetic materials obtained via fusing metallic powder with laser radiation in static magnetic field. The powder to be fused was prepared with milling the alloy containing rare-earth and transition metals. Austenitic stainless steel was used as a substrate material for obtaining samples. The structure of the magnets obtained was studied by means of SEM. EDS was used to estimate the distribution of elements in the samples. The study of magnetic properties showed the decrease of residual magnetization and coercivity in the magnets obtained with laser fusing as compared to raw material.
