Faculty Applied Sciences Department Fundamental Aspects of Materials and Energy Date 2010-04-27 Abstract The MnCoGe alloy can crystallize in either the hexagonal Ni2In- or the orthorhombic TiNiSi-type of structure. In both phases MnCoGe behaves like a typical ferromagnet with a second-order magnetic phase transition. For MnCoGeBx with B on interstitial positions, we discover a giant magnetocaloric effect associated with a single first-order magnetostructural phase transition, which can be achieved by tuning the magnetic and structural transitions to coincide. The results obtained on the MnCoGe-type alloys may be extensible to other types of magnetic materials undergoing a first-order structural transformation and can open up some possibilities for searching magnetic refrigerants for room-temperature applications Subject OA-Fund TU Delft To reference this document use: http://resolver.tudelft.nl/uuid:659e4e31-0428-4d23-a2c9-6bc00a03c33a DOI https://doi.org/10.1063/1.3399773 Publisher American Institute of Physics Source Appl.
