Phase diagram of disordered spin-Peierls systems
Maxim Mostovoy, Daniel Khomskii, Jasper Knoester
Abstract
We study the competition between the spin-Peierls and the antiferromagnetic ordering in disordered quasi-one-dimensional spin systems. We obtain the temperature vs disorder-strength phase diagram, which qualitatively agrees with recent experiments on doped CuGeO3.
