Magnetic polarons in Ca_(1-x)Y_xMnO_3
arXiv:cond-mat/0108284 · doi:10.1016/S0921-4526(02)00624-5
Abstract
Experimental evidence show that in the magnetoresistive manganite Ca_(1-x) Y_xMnO_3, ferromagnetic (FM) polarons arises in an antiferromagnetic (AF) background, as a result of the doping with Yttrium. This hypothesis is supported in this work by classical Monte Carlo (MC) calculations performed on a model where FM Double Exchange (DE) and AF Superexhange (SE) compite.
