Altermagnets are a type of antiferromagnet, a material in which the magnetic moments of atoms align in opposite directions, resulting in a net magnetic moment of zero. However, unlike traditional antiferromagnets, altermagnets exhibit unique magnetic and color reflectance properties, making them a fascinating subject for further study.
Hematite: A Unique Altermagnet
Hematite, a reddish mineral that occurs widely on Earth and Mars, has been the focus of numerous studies due to its magnetic and color reflectance properties, as well as its potential as a resource for future space missions.
