The magnetocaloric properties of rare-earth free Mn0.45Fe0.55NiSi1-ySny (y=0.12, 0.14, 0.16, and 0.18) alloys were studied. The raw material cost is significantly lower than the counterpart alloys containing Ge or Ga. Sn substitution reduced the Curie temperature (Tc) from 343 K (for y=0.12) to 248...
