Dark discrete breather modes in monoaxial chiral helimagnet with easy-plane anisotropy
I. G. Bostrem, E. G. Ekomasov, J. Kishine +2
Nonlinearity and discreteness are two pivotal factors for an emergence of discrete breather excitations in various media. We argue that these requirements are met in the forced fer…
Theory of standing spin waves in finite-size chiral spin soliton lattice
J. Kishine, Vl. E. Sinitsyn, I. G. Bostrem +4
We present a theory of standing spin wave (SSW) in a monoaxial chiral helimagnet. Motivated by experimental findings on the magnetic field-dependence of the resonance frequency in…
Coherent sliding dynamics and spin motive force driven by crossed magnetic fields in chiral helimagnet
Jun-ichiro Kishine, I. G. Bostrem, A. S. Ovchinnikov +1
We demonstrated that the chiral soliton lattice formed out of a chiral helimagnet exhibits coherent sliding motion by applying a time-dependent magnetic field parallel to the helic…
Magnetization and spin gap in two-dimensional organic ferrimagnet BIPNNBNO
V. E. Sinitsyn, I. G. Bostrem, A. S. Ovchinnikov +2
A magnetization process in two-dimensional ferrimagnet BIPNNBNO is analyzed. The compound consists of ferrimagnetic (1,1/2) chains coupled by two sorts of antiferromagnetic interac…
Bose-Einstein condensation of semi-hard bosons in S=1 dimerized organic compound F2PNNNO
I. G. Bostrem, V. E. Sinitsyn, A. S. Ovchinnikov
An analysis of the energy spectrum and the magnetization curve of two-dimensional organic antiferromagnet F2PNNNO with a spin-one dimerized structure shows that a behavior of the c…
Hidden Galilean symmetry, conservation laws and emergence of spin current in the soliton sector of chiral helimagnet
I. G. Bostrem, J. Kishine, R. V. Lavrov +1
Motivated by the spin current problem in chiral helimagnet, we rigorously elucidated the hidden Galilean invariance in the chiral XY model under the magnetic field. The Lie group a…
