Mean-field approach for skyrmion lattice in hexagonal frustrated antiferromagnets
Oleg I. Utesov
Simple mean-field approach for frustrated antiferromagnets on hexagonal lattices, aimed to describe the high-temperature part of the temperature-magnetic field phase diagram, is pr…

Effects of bond disorder and surface amorphization on optical phonon lifetimes and Raman peak shape in crystalline nanoparticles
Oleg I. Utesov, Sergei V. Koniakhin, Andrey G. Yashenkin
Optical phonons in nanoparticles with the randomness of interatomic bonds are considered both analytically and numerically. For weak dilute disorder two qualitatively different reg…
