Imry-Ma phase in O(n) models for space dimensions higher than the lower critical dimensionality
A. A. Berzin, A. I. Morosov, A. S. Sigov
Systems with continuous symmetry of the vector order parameter containing defects of the "random local field" or "random local anisotropy" types are investigated. It is shown that…
Quasi-one-dimensional Ising models with defects of the "random local field" type: Imry-Ma phase in spaces with dimension higher than the lower critical one
A. A. Berzin, A. I. Morosov, A. S. Sigov
The phase diagram in coordinates "temperature - concentration of defects" of quasi-one-dimensional Ising models with defects of the "random local field" type is investigated. The c…
Two-dimensional O(n) Models with Defects of "Random Local Anisotropy" Type
A. A. Berzin, A. I. Morosov, A. S. Sigov
The phase diagram of two-dimensional systems with continuous symmetry of the vector order parameter containing defects of the "random local anisotropy" type is investigated. In the…
Long-range order induced by random fields in two-dimensional O(n) models, and the Imry-Ma state
A. A. Berzin, A. I. Morosov, A. S. Sigov
The influence of defects of the "random local field" type with an anisotropic distribution of random fields on two-dimensional models with continuous symmetry of the vector order p…
Cubic anisotropy created by defects of "random local anisotropy" type, and phase diagram of the O(n) model
A. A. Berzin, A. I. Morosov, A. S. Sigov
The expression for the cubic-type-anisotropy constant created by defects of "random local anisotropy" type is derived. It is shown that the Imry-Ma theorem stating that in space di…
Imry-Ma disordered state induced by defects of "random local anisotropy" type in the system with O(n) symmetry
A. A. Berzin, A. I. Morosov, A. S. Sigov
For the system with the n-component order parameter (O(n)-model), conditions for initiation of the Imry-Ma disordered state resulting from the influence of defects of the "random l…
A Mechanism of Long-Range Order Induced by Random Local Fields: Effective Anisotropy Created by Defects
A. A. Berzin, A. I. Morosov, A. S. Sigov
We propose a microscopic mechanism of the long-range order in two-dimensional space induced by random local fields of crystal defects. The anisotropic distribution of defect-induce…
The anisotropy induced by defects of "random local field" type in O(n) models and suppression of the Imry-Ma inhomogeneous state
A. A. Berzin, A. I. Morosov, A. S. Sigov
We demonstrate that in the system with anisotropic distribution of the defect-induced random local field directions in the n-dimensional space of vector order parameter with the O(…
Phase Diagram of Multilayer Magnetic Structures
V. D. Levchenko, A. I. Morosov, A. S. Sigov
Multilayer "ferromagnet-layered antiferromagnet" (Fe/Cr) structures frustrated due to the roughness of layer interfaces are studied by numerical modeling methods. The "thickness-ro…
