Scientific Achievement
Discovered a new ferromagnetic metal, Cr1+xPt5-xP, with a high Curie temperature of 465 K and exceptionally strong magnetic anisotropy.
Significance and Impact
This work demonstrates a relatively unexplored strategy for materials discovery that combines high melting and low boiling elements. The approach provides a promising new route to new magnetic topological materials.
Research Details
- Cr1+xPt5-xP crystals were grown by the flux method, leveraging low-melting Pt-P eutectic based compositions.
- Transport and magnetization measurements indicate Cr1+xPt5-xP (x = 0.5) is a metallic ferromagnet with high Curie temperature of 465 K.
- M(H) isotherms show Cr1+xPt5-xP (x = 0.5) is exceptionally anisotropic with anisotropy fields of 345 kOe and 220 kOe at 1.8 K and 300 K respectively.
