Metamagnetic transition

  "id": "MLC-T-CHM-007261",
  "term": "Metamagnetic transition",
  "field": "Chemistry",
  "definition": "A magnetic phase transition where a material, initially in an antiferromagnetic or paramagnetic state, undergoes a sudden change to a ferromagnetic state upon application of a strong external magnetic field. This transition is characterized by a sharp increase in magnetization at a specific critical field strength. Such behavior is observed in certain intermetallic compounds and oxides, like FeRh alloys.",
