We present the results of an extensive study of the phase diagram and spin wave excitations for a general spin model on a hexagonal AB-stacked kagome system. The boundaries of the magnetic phases are determined via a combination of numerical (Monte C

We demonstrate using micromagnetic simulations and a theoretical model that a gradient in the saturation magnetization (${M}_{s}$) of a perpendicularly magnetized ferromagnetic film induces a nonreciprocal spin-wave propagation and, consequently, an

The magnetic field evolution of ground spin states of the stacked planar triangular antiferromagnet with antiferromagnetic interlayer interaction J c is explored using a minimal 3D classical Heisenberg model. A bi-quadratic coupling is also used to m

We present a detailed analysis of the magnetic states of monoclinic multiferroic systems as a function of temperature and magnetic field. The proposed nonlocal Landau free energy derived using symmetry arguments accounts well for the phase diagram of

The magnetic ordering in the stacked triangular antiferromagnet CsMnBr3 has been studied in an applied electric field. The value of the critical exponent β decreases from 0.245(5) (E = 0 V/cm) to 0.165(5) (E = 1.5 kV/cm). Our observations indicate t

Biquadratic {\it antisymmetric} exchange terms of the form $ - [C_{ij} e^{\alpha}_{ij}({\bf s}_i\times{\bf s}_j)_z]^2$, where ${\bf e}_{ij}$ is the unit vector connecting sites $i$ and $j$ and $\alpha = x,y$, due partially to magnetoelectric coupling
