Browsing: Antiferromagnetism

Antiferromagnetism is a phenomenon in materials science where the magnetic moments of atoms or ions in a crystalline material align in a regular pattern, with neighboring spins pointing in opposite directions. This type of magnetic order results in no net macroscopic magnetization because the magnetic moments cancel each other out. Antiferromagnetic materials are crucial in the field of spintronics and are used in various applications including memory devices, sensors, and as a means to suppress ferromagnetic behavior in magnetic storage media. Unlike ferromagnets, antiferromagnets become magnetically ordered below a certain temperature known as the Néel temperature, above which the material becomes paramagnetic and the magnetic ordering is lost. This behavior plays a key role in the study of superconductivity and complex electronic materials.
