These compounds exhibit an antiferromagnetic-ferrimagnetic transition of which the temperature can be adjusted by the Cr concentration. The transition temperature is at room temperature for x = 0.09. Magnetocaloric properties are presented as entropy-change and direct temperature-change. We show that these compounds have a narrow transitional hysteresis and exhibit the inverse magnetocaloric effect. We find a nearly hysteresis-free transition with a 2.6 K temperature-change around 287 K making it attractive for magnetic-cooling.eninfo:eu-repo/semantics/closedAccessFri metamagnetic transitionElectronic-structureSystemMn2sbPnictideMagnetocaloric effectMagnetic transitionTemperature changeScience & technologyPhysical sciencesPhysics, appliedPhysicsArticle000458371500001521510.1088/1361-6463/ab026e1361-6463
