Ferro and Antiferro magnetic
In a perfect antiferromagnetic (AFM) system, the number of up and down electrons is equal, not necessarily the atoms themselves. Having said that, simple AFM materials typically have only one "magnetic" species, so it is usually the case that their atomic magnetic moments have the same magnitude, and there are the same number of "up" and "down" atomic …

Recent experiments have proven that few-layer CrI${}_{3}$, a two-dimensional ferromagnetic insulator, orders antiferromagnetically between layers and shows very small critical fields, which allows for full electrical control of interlayer magnetism. Here, the authors propose a switching mechanism based on the formation of magnetic polarons, or ferrons. …

Antiferromagnetisme
Twee mogelijke spinoriëntaties van een antiferromagnetisch materiaal. Antiferromagnetisme is een vorm van magnetisme die optreedt in materialen die ongepaarde spins bevatten waartussen die wisselwerkingen die deze spins in tegengestelde richting willen plaatsen sterker zijn dan de wisselwerkingen die de spins evenwijdig …
Antiferromagnetism
Temperature Dependence. Antiferromagnetic material''s magnetic moments are temperature dependent and their critical temperature is the Neel temperature, (T_N), at which a magnetic phase change occurs [4].Typically (T_N) is found to be below room temperature but there are some exceptions [6].
