High relative cooling power iron based magnetocaloric nanoparticles.

Summary
We report in-situ high temperature X-ray diffraction and magnetocaloric measurements for (Fe70Ni30)92Mn8 alloy nanoparticles. At room temperature (RT), a mixture of a-FeNiMn and amorphous phase was observed, followed by transformation to the ?-FeNiMn phase at ~ 573 K. During cooling from 973 K to RT, the cell volume contracted, and the ?-FeNiMn phase was retained at RT. These nanoparticles show a moderate change in magnetic entropy and high relative cooling power.
