The performance of sintered permanent magnets with nucleation-type coercivity mechanism is largely governed by the magnetic state of thin surface layers of constituent grains, and a deeper insight into magnetization–demagnetization processes occurr

The possibilities of application of known models of domain structure to multiphase alloys are analyzed with the aim to assess the anisotropy constants and to search for magnetically uniaxial highly anisotropic phases. It is shown in what cases and ho

Magnetic refrigerants are used as heat exchangers to provide rapid heat transfer between magnetocaloric materials and heat-transfer liquid. An important question is how to turn bulk magnetocaloric materials into porous structures with superior heat t

A theoretical consideration of the processes of magnetization of orthorhombic crystals has been performed based on the Neel theory of magnetic phases. It has been established that orthorhombic magnets are characterized by linear magnetization curves.
