Lattice-Tuned Magnetism of Ru4+(4d4) Ions in Single-Crystals of the Layered Honeycomb Ruthenates: Li2RuO3 and Na2RuO3
J. C. Wang, J. Terzic, T. F. Qi +7
We synthesize and study single crystals of the layered honeycomb lattice Mott insulators Na2RuO3 and Li2RuO3 with magnetic Ru4+(4d4) ions. The newly found Na2RuO3 features a nearly…
Charge and orbital ordering in underdoped La1-xSrxMnO3
T. Mizokawa, D. I. Khomskii, G. A. Sawatzky
We have explored spin, charge and orbitally ordered states in La1-xSrxMnO3 (0 < x < 1/2) using model Hartree-Fock calculations on d-p-type lattice models. At x=1/8, several charge…
Interplay between orbital ordering and lattice distortions in LaMnO3, YVO3, and YTiO3
T. Mizokawa, D. I. Khomskii, G. A. Sawatzky
We have studied the interplay between orbital ordering, Jahn-Teller and GdFeO3-type lattice distortions in perovskite-type transition-metal oxides using model Hartree-Fock calculat…
Orbital polarization in LiVO_2 and NaTiO_2
S. Yu. Ezhov, V. I. Anisimov, H. F. Pen +2
We present a band structure study of orbital polarization and ordering in the two-dimensional triangular lattice transition metal compounds LiVO_2 and NaTiO_2. It is found that whi…
Origin of spin-gap in CaVO: effect of frustration and lattice distortion
O. A. Starykh, M. E. Zhitomirsky, D. I. Khomskii +2
We study the origin of spin-gap in recently discovered material CaVO. We analyze the spin- Heisenberg model on the depleted square lattice with nearest neighbor…
Long range Coulomb forces and the behaviour of the chemical potential of electrons in metals at a second order phase transition
D. van der Marel, D. I. Khomskii, G. M. Eliashberg
We give a general thermodynamic analyzis of the behaviour of the chemical potential of electrons in metals at a second order phase transition, including in our analysis the effect…
