Second Order Phase Transition

The ground state of a classical ferromagnet with the noncollinear single-ion anisotropy axes of the two sublattices and antisymmetric and anisotropic symmetric exchanges between the sublattices has been considered in a magnetic field applied in the hard magnetic directions of the crystal. The threshold conditions on the anisotropic interactions parameters determined the ground state among the three possible magnetic phases have been obtained. Depended on the type of the ground state and field direction the transition between the phases occurs as a phase transition first or second order. The value of the antisymmetric exchange above that the reorientation between two noncollinear phases is terminated by the second order phase transition depends on the angle between the local easy axes and the value of single-ion anisotropy. The field dependences of the magnetization and susceptibility have been calculated for the different ground states. The comparison with the results of the magnetic measurements in the highly anisotropic ferromagnet PbMnBO_4 has been made.

Practical Applications

The paper presents a comparative analysis of the magnetic properties of thin films of CoPt, CoPd, FePd alloys. The films were fabricated by electron-beam evaporation, with the variation of a ferromagnetic material content. Studies of the micromagnetic structure showed a decrease in the size of magnetic domains with an increase of the Co content in CoPt and CoPd films, which is associated with the presence of two magnetic phases in the films. Magneto-optical studies have shown abnormally high Faraday angles and the absence of the Kerr effect for CoPt films, which makes them attractive for practical applications in optics. The minimum coercive field values in magnetic field dependences of magnetization, as compared with other films, were obtained for FePd films, which is also associated with the peculiarities of the magnetic structure.

We study the magnetization and the magnetic phases of II-VI-based n-doped non-magnetic-semiconductor (NMS) / narrow to wide dilute-magnetic-semiconductor (DMS) / n-doped NMS quantum wells under in-plane magnetic field. The parallel magnetic field is used as a tool, in order to achieve non-step-like density of states in these -appropriate for conduction-band spintronics- structures.
