We report on structural, magnetic, and magnetocaloric properties of MnxFe1.95-xP0.50Si0.50 (x >= 1.10) compounds. With increasing the Mn:Fe ratio, a first-order magneto-elastic transition gradually changes into a first-order magneto-structural transition via a second-order magnetic transition. The study also shows that thermal hysteresis can be tuned by varying the Mn: Fe ratio. Small thermal hysteresis (less than 1 K) can be obtained while maintaining a giant magnetocaloric effect. This achievement paves the way for real refrigeration applications using magnetic refrigerants. (C) 2011 American Institute of Physics. [doi:10.1063/1.3634016]
