Spin-Lattice-Coupled Order in Heisenberg Antiferromagnets on the Pyrochlore Lattice

Effects of local lattice distortions on the spin ordering are investigated for the antiferromagnetic classical Heisenberg model on the pyrochlore lattice. It is found by Monte Carlo simulations that the spin-lattice coupling (SLC) originating from site phonons induces a first-order transition into t...
