La solution solide Cr1−xIrxO2

In silico CrNF, a half-metallic ferromagnetic nitride–fluoride mimicking CrO2

“…CrO 2 , one of the rare ferromagnetic oxides at room temperature (T C 400 K) and 2  B magnetization implicitly assigned to tetravalent Cr with 3d 2 configuration, is known for its use in magnetic recording applications [11]. Since its early discovery [12], several works were devoted to its physical properties [13]. DFT band structure calculations go beyond the phenomenological description by identifying a half metallic ferromagnet HMF behavior (ref.…”

High Oxygen Pressures and the Stabilization of Unusual Oxidation States of Transition Metals: Application to Iridium Oxides.

“…Table IV. Evolution of the (t2g eg) energy splitting versus the iridium oxidation state (n+) and the competing B'-O bond in the AjrB'O6, lattice * using Pauling's electronegativities 4. Conclusions The Table 4 shows that the local energy splitting (t2 g-eg ) for Irn+ is closely dependent on the n+ value, but also of the competing bond.…”
