Doubly degenerate orbital system in honeycomb lattice: implication of orbital state in layered iron oxide
J. Nasu, A. Nagano, M. Naka +1
We study a doubly-degenerate orbital model on a honeycomb attice. This is a model for orbital states in multiferroic layered iron oxides. The classical and quantum models are analy…

Magneto-Dielectric phenomena in charge and spin frustrated system of layered iron oxide
Makoto Naka, Aya Nagano, Sumio Ishihara
Dielectric and magnetic phenomena in spin and charge frustrated system RFe2O4 (R is a rare-earth metal ion) are studied. An electronic model for charge, spin and orbital degrees in…
