title: Dimensional crossover and charge order in half-doped manganites and cobaltites.
abstract: 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.
