Magnetization driven metal - insulator transition in strongly disordered Ge:Mn magnetic semiconductors
O. Riss, A. Gerber, I. Ya. Korenblit +3
We report on the temperature and field driven metal-insulator transition in disordered Ge:Mn magnetic semiconductors accompanied by magnetic ordering, magnetoresistance reaching th…
Current driven spin-wave instability triggered by the anomalous Hall effect
I. Ya. Korenblit
We studied the effect of strong electric current on spin waves interacting relativistically with the current. The spin-wave spectrum is calculated at arbitrary direction of the wav…
Quantum corrections to the spin-wave spectrum of LaCuO in an external magnetic field
I. Ya. Korenblit, A. Aharony, O. Entin-Wohlman
The effects of quantum fluctuations on the magnetic field dependence of the spin-wave gaps in the lamellar antiferromagnet LaCuO are considered. Nonlinear corrections to th…
Landau Expansion for the Kugel-Khomskii Hamiltonian
A. B. Harris, Amnon Aharony, O. Entin-Wohlman +2
The Kugel-Khomskii (KK) Hamiltonian for the titanates describes spin and orbital superexchange interactions between ions in an ideal perovskite structure in which the three $…
Hidden Symmetries and their Consequences in Cubic Perovskites
A. B. Harris, T. Yildirim, A. Aharony +2
The five-band Hubbard model for a band with one electron per site is a model which has very interesting properties when the relevant ions are located at sites with high (e. g.…
Neutron Scattering study of Sr_2Cu_3O_4Cl_2
Y. J. Kim, R. J. Birgeneau, F. C. Chou +10
We report a neutron scattering study on the tetragonal compound Sr_2Cu_3O_4Cl_2, which has two-dimensional (2D) interpenetrating Cu_I and Cu_{II} subsystems, each forming a S=1/2 s…
