IEEE Magnetics Letters, 10.1949-307X1949-3088https://doi.org/10.1109/LMAG.2019.2955667https://ieeexplore.ieee.org/document/8913622http://hdl.handle.net/11452/30755The magnetic and magnetocaloric properties of a new Mn27Cr7Ni33Ge25Si8 high-entropy alloy (HEA) were investigated. The crystal structure is characterized through multiphase Rietveld refinement of X-ray diffraction data. The structure of the HEA is orthorhombic in the Pnma space group. Arrott plots indicate that the ferromagnetic-paramagnetic phase transition is of second order. The maximum magnetic entropy change is 2.49 J.kg(-1).K-1, among the highest reported for alloys that do not contain rare earth elements.eninfo:eu-repo/semantics/closedAccessEngineeringPhysicsElectromagneticsHigh-entropy alloysMagnetic materialsSoft magnetic propertiesMagnetocaloric effectRoom-temperatureBehaviorFeNiCoRefrigerationGlassTbGdCrystal structureEntropyHigh-entropy alloysMagnetic hysteresisMagnetic materialsMagnetic propertiesMetalsRare earthsRietveld refinementSoft magnetic materialsTemperature measurementAmorphous magnetic materialsFerromagnetic-paramagnetic phase transitionMagnetic entropy changeMagnetocaloric effect (MCE)Magnetocaloric propertiesOrthorhombic structuresSoft magnetic propertiesX-ray diffraction dataMagnetocaloric effectsArticle0005151712000012-s2.0-8507591894410Engineering, electrical & electronicPhysics, appliedMagnetism; Manganites; Critical Behavior
