· FeRh

FeRh is an intermetallic compound combining iron and rhodium, belonging to the class of transition metal alloys known for their magnetic and thermal properties. This material is primarily studied in research contexts for its magnetocaloric and magnetostructural characteristics, particularly its temperature-dependent magnetic phase transitions. FeRh is of interest in advanced applications requiring precise control of magnetic behavior across temperature ranges, though it remains largely experimental rather than widely deployed in conventional engineering.
