The influences of boron addition on the phase formation, Curie temperature and magnetic entropy change of the Mn 0.95 Fe 1.05 P 0.5 As 0.5 compound have been investigated. All the samples crystallize in the hexagonal Fe 2 P-type structure and boron enters into the basal plane as an interstitial element. The Curie temperatures can be adjusted by varying the boron content. Strong field-induced itinerant-electron meta-magnetic transitions with small hysteresis are observed. With boron addition in small amounts the giant-magnetocaloric effects are slightly enhanced. This study provides a novel route to tune optimal working temperatures and improve magnetic properties and magnetocaloric effect.
