Helical magnetic structures above the Curie point

The behavior of a ferromagnet with the absence of mirror symmetry in the region above the Curie point has been studied. It is shown that the presence of a pseudoscalar of mrot m type in the system leads to the transition point smearing and to the generation of a new large-scale magnetic structure ab...

Description
Summary:The behavior of a ferromagnet with the absence of mirror symmetry in the region above the Curie point has been studied. It is shown that the presence of a pseudoscalar of mrot m type in the system leads to the transition point smearing and to the generation of a new large-scale magnetic structure above the Curie point. The obtained result may be of importance in the study of the maintenance of the dipole component of magnetic fields of the Earth.
