Spontaneous Hall effect in the Weyl semimetal candidate of all-in all-out pyrochlore iridate

Material with both topological state and magnetic order remains rare. Here, Ueda et al. observe a sizable spontaneous Hall conductivity with minimal magnetization at a few Kelvin below the all-in-all-out magnetic ordering temperature in the predicted magnetic Weyl semimetal R 2Ir2O7.
