Combined Effect of Bond- and Potential-Disorder in Half-Doped Manganites
arXiv:0706.1425 · doi:10.1103/PhysRevLett.100.076406
Abstract
We analyze the effects of both bond- and potential-disorder in the vicinity of a first-order metal insulator transition in a two-band model for manganites using a real-space Monte Carlo method. Our results reveal a novel charge-ordered state coexisting with spin-glass behavior. We provide the basis for understanding the phase diagrams of half-doped manganites, and contrast the effects of bond- and potential-disorder and the combination of both.
