On flat bands in the -- XXZ sawtooth chain
Vadim Ohanyan, Johannes Richter, Michael Sekania +3
We consider a generalization of the XXZ model on the sawtooth spin chain with Dzyaloshinskii-Moriya interactions in which all exchange constants (symmetric, antisymmetric, and axia…
The magnetization process of classical Heisenberg magnets with non-coplanar cuboc ground states
Johannes Richter, Heinz-Jürgen Schmidt, Jürgen Schnack
We consider a classical Heisenberg model on the kagomé and the square kagomé lattice, where at zero magnetic field non-coplanar cuboctahedral ground states with twelve sublattices…
Exotic magnetization curves in classical square-kagomé spin lattices
Heinz-Jürgen Schmidt, Johannes Richter
Classical spin systems with non-coplanar ground states typically exhibit nonlinear magnetization curves characterized by kinks and jumps. Our article briefly summarizes the most im…
