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…
Monte Carlo study of half-magnetization plateau and magnetic phase diagram in pyrochlore antiferromagnetic Heisenberg model
Yukitoshi Motome, Karlo Penc, Nic Shannon
The antiferromagnetic Heisenberg model on a pyrochlore lattice under external magnetic field is studied by classical Monte Carlo simulation. The model includes bilinear and biquadr…
The Truncated Polynomial Expansion Monte Carlo Method for Fermion Systems Coupled to Classical Fields: A Model Independent Implementation
G. Alvarez, C. Sen, N. Furukawa +2
A software library is presented for the polynomial expansion method (PEM) of the density of states (DOS) developed by two of the authors (N.F. and Y. M.). The library provides all…
Entropy-Driven Reentrant Behavior in CMR Manganites
Nobuo Furukawa, Yukitoshi Motome, Naoto Nagaosa
We discuss the origin of the reentrant behaviors of insulating states above the Curie temperature of the colossal magnetoresistance manganites. We consider a system where charge or…
An Origin of CMR: Competing Phases and Disorder-Induced Insulator-to-Metal Transition in Manganites
Yukitoshi Motome, Nobuo Furukawa, Naoto Nagaosa
We theoretically explore the mechanism of the colossal magnetoresistance in manganese oxides by explicitly taking into account the phase competition between the double-exchange fer…
Orbital ordering and one-dimensional magnetic correlation in vanadium spinel oxides AV2O4 (A = Zn, Mg, or Cd)
Yukitoshi Motome, Hirokazu Tsunetsugu
We present our theoretical results on the mechanism of two transitions in vanadium spinel oxides VO (=Zn, Mg, or Cd) in which magnetic V cations constitute a geometri…
