Antiferromagnets are materials with a so-called hidden magnetic order. This means that they have magnetic domains with a distinguished spin direction, but the magnetization is zero, so that it is impossible to detect such domains by measuring the magnetic moment. Partly, therefore, antiferromagnets were considered interesting, but absolutely useless for practical purposes by materials, in contrast, for example, from ferromagnets. During just one year the situation changed dramatically. Now antiferromagnets are considered the basis of future electronics and the main contenders for the creation of superfast and compact memory and even logical elements with terraced speed. In this report, I will talk about the main achievements of antiferromagnetic spintronics and those scientific problems in this field that, in my opinion, are of fundamental interest.
