We employ the combination of the density functional theory and the dynamical mean-field theory to investigate the electronic structure and magnetic properties of SrCoO(3), monocrystals of which were prepared recently. Our calculations lead to a ferromagnetic metal in agreement with experiment. We find that, contrary to some suggestions, the local moment in SrCoO(3) does not arise from intermediate spin state, but is a result of coherent superposition of many different atomic states. We discuss…

Negative Charge-Transfer Energy in SrCoO2.5 Thin Films: An Interplay between O-2p Hole Density, Charge-Transfer Energy, Charge Disproportionation, and Ferromagnetic Ordering
SrCoO2.5 (SCO) bulk is found to be a charge-transfer insulator with a positive value of charge-transfer energy (Δ) and 3d6 ground state, which achieves the antiferromagnetic nature through conventi...
Spin state crossover and colossal magnetoresistance in barium-doped cobaltites
Abstract Investigation of the crystal structure, magnetic and transport properties of both the stoichiometric and anion-deficient Ba 2+ -doped lanthanum cobaltites was performed. Anomalous
Spectroscopic aspects of the magnetic interaction in SrCoO2.75 and SrCoO3 thin films
Abstract The origin of the magnetic interaction in SrCoO2.75 and SrCoO3 thin films has been investigated with the help of their experimental valence band (VB) and the conduction band (CB) at room
The condition for a large magnetoresistance effect in perovskite cobaltites
The magnetic and magnetotransport properties of the anion-deficient perovskites La1–xBaxCoO3–δ are studied. It is shown that a gradual transition from the metallic to the semiconductor conduction and
Robust Ferromagnetism in Highly Strained SrCoO3 Thin Films
Epitaxial strain provides important pathways to control the magnetic and electronic states in transition metal oxides. However, the large strain is usually accompanied by a strong reduction of the
Real-space charge distribution of the cobalt ion and its relation with charge and spin states
The charge state of an ion provides a simplified electronic picture of the bonding in compounds, and heuristically explains the basic electronic structure of a system. Despite its usefulness, the
Robust half-metallicity of hexagonal SrNiO3
Abstract In the rich panorama of the electronic and magnetic properties of 3d transition metal oxides SrMO3 (M=Ti, V, Cr, Mn, Fe, Co, Ni, Cu), one member (SrNiO3) is missing. In this paper we use
Pressure induced antiferromagnet-ferromagnet transition in La0.5Ba0.5CoO2.8 cobaltite
Abstract The anion deficient cobaltite La0.5Ba0.5CoO2.8 with the formal cobalt valence state close to 3+ has been studied as function of pressure up to 6.5 GPa at different temperatures by neutron
Role of oxygen vacancy in the spin-state change and magnetic ordering in SrCoO3−δ
We present the first-principles investigation of the structural, electronic, and magnetic properties of SrCoO$_{3-\delta}$ ($\delta=0, 0.25, 0.5$) to understand the multivalent nature of Co ions in
Localized-itinerant dichotomy and unconventional magnetism in SrRu2O6
It is found that the strong hybridization between Ru d and O p states results in a Ru valence that is closer to +4, leading to the small ordered moment ~1.2 μB, consistent with a DFT prediction, and correlation effects are found to play a significant role.
