Magnetism of CaRuO3 crystal

The effects of strain on crystal structure and properties during epitaxial growth of oxides

“…While both materials are good conductors, their magnetic properties differ substantially. SrRuO 3 is ferromagnetic with Curie temperature of 165 K; CaRuO 3 is paramagnetic at all temperatures (Callagha, Moeller, & Ward, 1966;Koriyama et al, 2004;Randall & Ward, 1959). Using density-functional theory, Zayak et al predicted that SRO and CRO magnetic properties can be radically altered by a strain of 2e3% (Zayak, Huang, Neaton, & Rabe, 2008), which makes SRO and CRO materials perfect candidates for the study of the straineproperty relationship.…”

99Ru and61Ni Mössbauer spectroscopic studies using the accelerator at RIKEN

“…A small-crystal sample of CaRuO 3 was found to be mostly composed of rough cubes of 0.5 mm 3 . These crystals were characterized by XRD, EPMA, magnetization and electrical resistivity measurements [3], 99 Ru Mössbauer spectroscopy, and µSR method.…”

Integer spin-chain antiferromagnetism of the 4doxide CaRuO3with post-perovskite structure

“…Besides, a possible hidden magnetic order was suggested by anomalous Hall-effect [14]. It appears that the magnetically critical behavior of the perovskite CaRuO 3 is still highly under debated [15][16][17][18][19][20][21].…”
