Claim Text:
1. A method of preparing a boron-doped transition metal pnictide magnetocaloric material, the method comprising: contacting heat-treating the eutectic mixture to prepare the boron-doped transition metal pnictide magnetocaloric material wherein the transition metal halide includes a plurality of transition metal halides, and wherein transition metal halides of the plurality of transition metal halides form eutectic mixture that melts during the heat-treating, the reducing metal forms a first reducing metal halide during the heat-treating, and the first reducing metal halide and the transition metal halide form a eutectic mixture that melts during the heat-treating, the reducing metal includes a plurality of reducing metals, wherein the plurality of reducing metals forms a plurality of reducing metal halides during the heat-treating, and wherein second and third reducing metal halides of the plurality of reducing metal halides form a eutectic mixture that melts during the heat-treating, or further comprising a fourth reducing metal halide, wherein the fourth reducing metal halide and the transition metal halide form a eutectic mixture that melts during the heat-treating, or the fourth reducing metal halide and the first reducing metal halide form a eutectic mixture that melts during the heat-treating, or further comprising a plurality of reducing metal halides, wherein compounds of the plurality of reducing metal halides form a eutectic mixture that melts during the heat-treating.
