Easy-plane antiferromagnet in tilted field: gap in magnon spectrum and susceptibility
Artemiy S. Sherbakov, Oleg I. Utesov
Motivated by recent experimental data on dichloro-tetrakis thiourea-nickel (DTN) [T.A. Soldatov , Phys. Rev. B , 104410 (2020)], a model of antiferromagn…
Coupled oscillators model for hybridized optical phonon modes in contacting nanosized particles and quantum dot molecules
S. V. Koniakhin, O. I. Utesov, A. G. Yashenkin
Modification of optical phonon spectra in contacting nanoparticles as compared to the single ones is studied. Optical phonons in dielectric and semiconducting particles obey the Eu…
Small-angle neutron scattering in fully polarized phase of non-collinear magnets with interfacial-like DMI
Oleg I. Utesov
Spin waves in non-collinear magnets with symmetry are discussed in the context of inelastic neutron scattering in small-angle scattering geometry. In the framework of a mi…
Spin wave stiffness and damping in a frustrated chiral helimagnet CoZnMn as measured by small-angle neutron scattering
V. Ukleev, K. A. Pschenichnyi, O. Utesov +7
Multiple intriguing low temperature phenomena have recently been discovered in the family of chiral cubic Co-Zn-Mn compounds with Mn-type structure. In particular, CoZn…
Transition between long and short-range helical orders in mixed B20 cubic helimagnets
Oleg I. Utesov
A model of B20 helimagnet with strong (frustrating) defect bonds is considered. Single defect provides dipolar field-like distortion of the helical magnetic ordering. At finite def…
Magnetodipolar interaction and quasiparticles delocalization in disordered quantum magnets
Oleg I. Utesov
It is well-known that disordered quantum magnets usually host localized elementary excitations in gapped phases. Here we show that long-range magnetodipolar interaction can lead to…
