چکیده
MnMX (M = Co or Ni, X Si Ge) alloys, experiencing structural transformation between Ni2In-type hexagonal and TiNiSi-type orthorhombic phases, attract considerable attention due to their potential applications as room-temperature solid refrigerants. Although lots of studies have been carried out on how tune this obtain large entropy change in a wide temperature region, the crystallography martensitic is still unknown. The biggest obstacle for investigation bulk sample, which phases coexist, because alloys will fragment into powders after transformation. For reason, we carefully be slightly below 300 K. In that case, sample with small amounts distributed matrix obtained. Most importantly, there are no cracks two phases. It facilities us investigate microstructure using electron microscope. obtained results indicate orientation relationship structures [42¯2¯3]h//[120]o & (011¯0)h//(001)o habit plane {2¯113.26}h. WLR theory also adopted calculate plane. calculated result agrees well measured one. Our work reveals hexagonal-orthorhombic first time helpful understanding transformation-associated physical effects alloys.

Ti substitution for Mn in MnCoGe - The magnetism of Mn0.9Ti0.1CoGe
Bulk magnetization measurements (5-320 K; 0-8T) reveal that below room temperature Mn0.9Ti0.1CoGe exhibits two magnetic phase transitions at ~178 K and ~280 K. Neutron diffraction measurements (3-350K) confirm that the transition at ~178K is due to the structural change from the low-temperature orthorhombic TiNiSi-type structure to the higher temperature hexagonal Ni2In-type structure while the...
