Title<br />
EUROINVENT <strong>2012</strong><br />
selection of alloy composition and production process<br />
parameters to obtain hard magnetic materials with unique<br />
nanostructure. Obtained TbCu7 type of structure is<br />
characterized by stable or abnormal (positive) coercivity<br />
and remanence parameters in wide temperature range. The<br />
production of such materials is extremely hard due to<br />
metastable character of desired crystalline phase. Projects<br />
related with described functional materials are counted to<br />
the so called “cutting edge” topics in manufacturing<br />
magnetic materials. Summarizing, due to unique thermomagnetic<br />
properties these materials are extremely<br />
interesting for companies prducing high temperature<br />
sensors and motors working in harsh conditions.<br />
