Abstract The layered-ruthenate family of materials possess an intricate interplay of structural, electronic and magnetic degrees of freedom that yields a plethora of delicately balanced ground states. This is exemplified by Ca3Ru2O7, which hosts a co

Abstract B-site ordered 4d 1 and 5d 1 double perovskites have a number of potential exotic ground states including multipolar order, quantum spin liquids and valence bond glass states. These arise from the complex interactions of spin-orbital entangl

MgV_{2}O_{4} is a spinel based on magnetic V^{3+} ions, which host both spin (S=1) and orbital (l_{eff}=1) moments. Owing to the underlying pyrochlore coordination of the magnetic sites, the spins in MgV_{2}O_{4} only antiferromagnetically order once

Sr3Ru2O7 exhibits a quantum critical point tunable by magnetic field and has been widely used in the study of criticality. Here, by using inelastic neutron scattering, the authors measure collective magnetic excitations near the quantum critical poin

Abstract Discrepancies in the low-energy quasiparticle dispersion extracted from angle-resolved photoemission, scanning tunneling spectroscopy, and quantum oscillation data are common and have long haunted the field of quantum matter physics. Here, w

We report a comprehensive experimental investigation of the magnetic structure of the cycloidal phase in Ca_{3}Ru_{2}O_{7}, which mediates the spin reorientation transition and establishes its magnetic phase diagram. In zero applied field, single-cry

The role of the lattice in the correlated metal-insulator transition of Ca2RuO4 has led to significant interest but experiments that are at the same time sensitive to crystal and electronic structure are difficult. Riccò et al. successfully combine
