We study an anisotropic Heisenberg antiferromagnet with ferromagnetic transverse spin exchange using exact quantum Monte Carlo methods. Such a model is relevant to a class of rare earth tetraboride materials that display a range of magnetization plateaus under applied magnetic field. The layered arrangement of magnetic ions in these materials is topologically equivalent to the Shastry-Sutherland lattice. In this frustrated geometry, we study the interplay of next-nearest neighbor interactions…

Fractional magnetization plateaus and magnetic order in the Shastry-Sutherland magnet TmB4.
TLDR
Using an effective S=1/2 model and its equivalent two-dimensional fermion gas, it is suggested that the magnetic properties of TmB4 are related to the fractional quantum Hall effect of a 2D electron gas.
