CrSb (Chromium Antimonide)

A binary transition-metal pnictide crystallizing in the hexagonal NiAs-type structure, space group P6₃/mmc. It is a prominent candidate altermagnet, a newly recognized magnetic class combining zero net magnetization (like an antiferromagnet) with spin-split electronic bands (like a ferromagnet); CrSb hosts a high magnetic ordering temperature (T_N well above room temperature, ~700 K) and a large momentum-dependent spin splitting confirmed by photoemission. This robust, room-temperature altermagnetic order makes CrSb a leading platform for studying altermagnetism, spin-split transport, and antiferromagnetic spintronics without stray magnetic fields.
