Study of the One- and Two-Band Models for Colossal Magnetoresistive Manganites Using the Truncated Polynomial Expansion Method
C. Sen, G. Alvarez, Y. Motome +5
Considerable progress has been recently made in the theoretical understanding of the colossal magnetoresistance (CMR) effect in manganites. The analysis of simple models with two c…
Flat-Bands on Partial Line Graphs -- Systematic Method for Generating Flat-Band Lattice Structures
Shin Miyahara, Kenn Kubo, Hiroshi Ono +2
We introduce a systematic method for constructing a class of lattice structures that we call ``partial line graphs''.In tight-binding models on partial line graphs, energy bands wi…
Mechanism for lifting the degeneracy in the double-exchange spin ice model on a kagomé lattice: Dodecamer formation
Yoshihiro Shimomura, Shin Miyahara, Nobuo Furukawa
We investigated the double-exchange spin ice model on a kagomé lattice by Monte Carlo simulation in order to study a mechanism for lifting the degeneracy in frustrated electron sys…
Orbital Ordering in ferromagnetic Lu2V2O7
H. Ichikawa, L. Kano, M. Saitoh +7
We have observed the orbital ordering in the ferromagnetic Mott-insulator Lu2V2O7 by the polarized neutron diffraction technique. The orbital ordering pattern determined from the o…
