Research into magnetism has traditionally recognized two main types: ferromagnets and antiferromagnets. Ferromagnets are commonly known for their ability to attract metals, while antiferromagnets exhibit hidden magnetism at the atomic level.
The emergence of altermagnets could provide valuable insights into magnetic properties that have yet to be fully understood. These materials may represent a significant advancement in the field of magnetism.
Diamond quantum sensors, which are at the forefront of this research, may play a crucial role in detecting these elusive altermagnets, potentially paving the way for breakthroughs in magnetic technology.
