“…Experimentally, several pyrochlore iridates are observed to undergo magnetic ordering, and experiments have now confirmed that the order is of the predicted AIAO form (Disseler, 2014;Donnerer et al, 2016;Guo et al, 2016;Sagayama et al, 2013). The magnetically ordered pyrochlores, such as A=Eu, Nd are seen, in clean samples, to be insulating at low temperatures Tafti et al, 2012;Tian et al, 2016;Ueda et al, 2012Ueda et al, , 2015b.…”
