Phase Transition and Thermal Order-by-Disorder in the Pyrochlore Quantum Antiferromagnet Er2Ti2O7: a High-Temperature Series Expansion Study
J. Oitmaa, R. R. P. Singh, A. G. R. Day +2
Several rare earth magnetic pyrochlore materials are well modeled by a spin-1/2 quantum Hamiltonian with anisotropic exchange parameters Js. For the Er2Ti2O7 material, the Js were…

Exact solution and high temperature series expansion study of the 1/5-th depleted square lattice Ising model
Simeon Hanks, Trinanjan Datta, Jaan Oitmaa
The critical behavior of the 1/5-depleted square-lattice Ising model with nearest neighbor ferromagnetic interaction has been investigated by means of both an exact solution and a…
