Electronic Properties of Pyrochlore-Type Ca2Ir2O7
arXiv:2211.09290 · doi:10.7566/JPSJ.91.125002
Abstract
The electrical resistivity, magnetic susceptibility, and heat capacity of sintered samples of Ca2Ir2O7, in which pentavalent Ir atoms with 5d4 electron configuration form a pyrochlore structure, have been studied. The obtained experimental data strongly suggest that Ca2Ir2O7 is metallic below room temperature and exhibits no electronic or magnetic phase transitions above 0.12 K.
