It was demonstrated a presence of weak antiferromagnetic interaction between components of ferromagnetic twins through the twins boundaries. Pulses of asymmetrical magnetic fields were proposed to use for the control of ratchet-like motion of domain walls in antiferromagnetics which allowed to get rid of any restrictions on size, conductivity and crystal structure of antiferromagnetic materials. The phenomenological theory of uniaxial antiferromagnetics with Dzyaloshinsky-Moria interaction was elaborated. In particular spin-orbit torques induced by current tacking into consideration of already investigated spin-transfer torques were studied. The peculiarities of spin ultrafast dynamics of photoinduced magnetization in collinear compensated antifferomagnetics were revealed. A crucial role of antiferromagnetic vector in photoinduced phase transitions which was previously neglected has been demonstrated. This is extremely important for the creation of field controlled ultrahigh frequency generators and filters which can be integrated in modern electronic microchips.
