Chemical compound
Gadolinium phosphide is an inorganic compound of gadolinium and phosphorus with the chemical formula GdP.[1][2]
Synthesis
Gadolinium phosphide can be obtained by reacting gadolinium and phosphorus at high temperature, and single crystals can be obtained by mineralization.[3]
- 4 Gd + P4 → 4 GdP
Physical properties
GdP has a NaCl-structure and transforms to a CsCl-structure at 40 GPa.[4]
GdP forms crystals of a cubic system, space group Fm3m.[5][6]
Gadolinium phosphide is antiferromagnetic.[citation needed]
Uses
The compound is a semiconductor used in high power, high frequency applications and in laser diodes.[1][7]
