Phys. Rev. Lett. 91, 036401 (2003) [4 pages]Dimensional Crossover and Charge Order in Half-Doped Manganites and CobaltitesReceived 15 February 2002; published 15 July 2003 We propose a generic model for understanding the effect of quenched disorder on charge-ordering in half-doped manganese and cobalt oxides with different crystal structures. Current experimental observations are explained in the light of the global phase diagram of the model. © 2003 The American Physical Society URL:
