Magnetotransport of Sm2Ir2O7 across the pressure-induced quantum-critical phase boundary
Abstract Rare-earth pyrochlore iridates host two interlocking magnetic sublattices of corner-sharing tetrahedra and can harbour a unique combination of frustrated moments, exotic excitations and highly correlated electrons.They are also the first systems predicted to display both topological Weyl semimetal and axion insulator phases.We have measure
