Competing anisotropies in the chiral cubic magnet CoZnMn unveiled by resonant x-ray magnetic scattering
Victor Ukleev, Oleg I. Utesov, Chen Luo +11
The cubic -Mn-type alloy CoZnMn is a chiral helimagnet that exhibits a peculiar temperature-dependent behavior in the spiral pitch, which decreases from 130 nm at ro…

Magnetoroton in a two-dimensional Bose-Bose mixture
O. I. Utesov, S. V. Andreev
We extend our theory of slow magnons in a two-component Bose-Einstein condensate to the case of two spatial dimensions (2D). We provide a detailed discussion of polaronic correctio…

Raman peak shift and broadening in crystalline nanoparticles with lattice impurities
S. V. Koniakhin, O. I. Utesov, A. G. Yashenkin
The effect of point-like lattice impurities on nanoparticle Raman spectra (RS) is studied using both numerical and analytical methods. Particular cases of replacement atoms of vari…
