Spin, Orbital, and Spin-Orbital Polarons in Transition Metal Oxides
نویسنده
چکیده
I give a brief overview of a polaron formation in three distinct transition metal oxides: (i) spin polaron when a hole is added to the antiferromagnetic (AF) ordered plane in La2CuO4, (ii) orbital polaron when a hole is added to the alternating orbital (AO) ordered plane in LaMnO3, and (iii) spin-orbital polaron when a hole is added to the AF and AO ordered plane in LaVO3. Comparison of the distinct features of the above polarons can shed some light on the basic differences between the experimental phase diagrams of the lightly doped transition metal oxides La2−xSrxCuO4, La1−xSrxMnO3, and La1−xSrxVO3.

Novel photoinduced phase transitions in transition metal oxides and diluted magnetic semiconductors
Some transition metal oxides have frustrated electronic states under multiphase competition due to strongly correlated d electrons with spin, charge, and orbital degrees of freedom and exhibit drastic responses to external stimuli such as optical excitation. Here, we present photoemission studies on Pr0.55(Ca1 - ySry)0.45MnO3 (y = 0.25), SrTiO3, and Ti1 - xCoxO2 (x = 0.05, 0.10) under laser ill...
متن کاملHigh spin systems with orbital degeneracy.
High-spin systems with orbital degeneracy are studied in the large spin limit. In the absence of Hund's coupling, the classical spin model is mapped onto disconnected orbital systems with spins up and down, respectively. The ground state of the isotropic model is an orbital valence bond state where each bond is an orbital singlet with parallel spins, and neighboring bonds interact antiferromagn...
متن کاملDimerization and Entanglement in Spin-Orbital Chains
Spin-orbital coupling: The study of orbital degeneracy in transition metal oxides is motivated, e.g., by the large variety of spin-charge-orbital ordered phases, the possible control of the orbital degree of freedom at interfaces and heterostructures, the switching from orbital ordered to metallic phases in applied magnetic fields, and the colossal magnetoresistance. The rather complex interpla...
متن کاملFirst-principles investigations of the orbital magnetic moments in CrO2
The electronic and magnetic properties of the ferromagnetic half-metal CrO2 have been studied by using the full-potential linear muffin-tin orbital method within the local-spin-density approximation ~LSDA! and the LSDA1U approach. The orbital magnetic moments are investigated by including the spin-orbit coupling in both schemes. Compared with the orbital contributions to magnetization in other ...
متن کاملViewpoint Orbital Engineering , By Design
Oxides containing transition metals have many fascinating properties, such as superconductivity, ferroelectricity, and forms of magnetism that are linked to the crystal structure. These properties depend on the charge and spin of the transition metal ion and which of its orbitals are occupied by electrons. Tuning these degrees of freedom, however, requires exquisite control over the material’s ...
