Magnetic materials

Over the 30 years’ history of the group’s activity, such magnetic materials as Alnico (cast and sintered) and rare-earth-metals based, mostly Nd-Fe-B, were studied. The processing methods comprised sintering of powders, mechanical alloying, rapid solidification from melt and hydrogenation methods (HD and HDDR). The latter techniques are applied for recycling of sintered, scrap magnets, for fabrication of coercive powders for polymer bonded magnets.
In addition to the hard magnetic materials, magnetic shape memory alloys, magnetocaloric alloys and soft magnetic materials are also studied.
