Quantum magnets with large single-ion easy-plane anisotropy in transverse magnetic field
A. V. Sizanov, A. V. Syromyatnikov
We discuss low-temperature properties of magnets with integer spin and large single-ion easy-plane anisotropy in transverse magnetic field . Considering the exchange interac…

Novel approach to description of quantum magnets with large singe-ion easy-plane anisotropy
Alexey V Sizanov, Arseny V Syromyatnikov
We introduce a new representation of an integer spin via bosonic operators which is useful in describing the paramagnetic phase and transitions to magnetically ordered phases i…

Antiferromagnet with two coupled antiferromagnetic sublattices in a magnetic field
Alexey V Sizanov, Arseny V Syromyatnikov
We discuss the magnon spectrum of an antiferromagnet (AF) in a magnetic field consisting of two interpenetrating AF sublattices coupled by the exchange interaction at T=0. One-…
