Physical Review B
CaCrO 3 is at the crossover from localized to itinerant electronic behavior, and interpretation of its electronic state has remained controversial. It is a metal from an optical study. However, the collinear type-C antiferromagnetic spin ordering below T N ≈ 90 K is characteristic of localized electron magnetism. We have performed many runs of high-pressure synthesis. CaCrO 3 crystals can be found in some batches. We have used specific-heat measurement as a diagnostic tool to probe thedoi:10.1103/physrevb.92.144421 fatcat:q3aucg65vfcbpmkwo7nusj7uf4
