The spin-wave spectrum of the Jahn-Teller system LaTiO3
Robert Schmitz, Ora Entin-Wohlman, Amnon Aharony +2
We present an analytical calculation of the spin-wave spectrum of the Jahn-Teller system LaTiO3. The calculation includes all superexchange couplings between nearest-neighbor Ti io…
The magnetic structure of the Jahn-Teller System LaTiO3
Robert Schmitz, Ora Entin-Wohlman, Amnon Aharony +2
We investigate the effect of the experimentally observed Jahn-Teller distortion of the oxygen octahedra in LaTiO3 on the magnetic exchange. We present a localized model for the eff…
Periodic Molecular Arrangements from Space Groups
Ravi Sachidanandam, A. B. Harris
We demonstrate, using examples from and -dimensions, a systematic method of finding all possible periodic arrangements of a given molecule or molecules such that the arrange…
Magnetic anisotropies and general on--site Coulomb interactions in the cuprates
O. Entin-Wohlman, A. B. Harris, Amnon Aharony
This paper derives the anisotropic superexchange interactions from a Hubbard model for excitations within the copper 3d band and the oxygen 2p band of the undoped insulating cuprat…
