Abstract

Several pyrochlore antiferromagnets are being considered as candidate materials where geometrical frustration may lead to quantum spin-liquid states. In a ``breathing'' pyrochlore lattice systems (see PRL 110, 097203 (2013)) the spins occupy the vertices of alternating tetrahedra of different size that are characterized by different exchange parameters J and J^\ensuremath'.
