Abstract (300 words maximum)
The magnetocaloric effect is an important phenomenon because it can be used to create more efficient cooling technology than conventional gas compression cooling. Additionally, it is more environmentally friendly since it doesn’t use ozone depleting gases. The MM'X alloy CrNiP is a promising magnetocaloric material based on recent theoretical studies. The magnetocaloric effect stems from a magnetostructural coupling in this family, which creates a large entropy change over a wide temperature range, optimal for magnetic cooling technology. In this presentation we will discuss the structural analysis of the CrNiP1-xSbx solid solutions using powder X-ray diffraction. With only a small percentage of Sb dopant into CrNiP1-xSbx we see the material transition from the orthorhombic CrNiP structure to the hexagonal Ni2In-type structure. As a result, the structural variation in CrNiP1-xSbx can be used to tune the potential magnetocaloric effect which will be analyzed in our future studies.
