Phase diagram of the antiferromagnetic $J_{1}$ - $J_{2}$ spin- $1$ pyrochlore Heisenberg model

Imre Hagymási, Nils Niggemann, Johannes Reuther

We study the phase diagram of the antiferromagnetic $J_{1}$ - $J_{2}$ Heisenberg model on the pyrochlore lattice with $S = 1$ spins at zero and finite temperatures. We use a combination of…
