摘要：

A theory is developed to describe the hopping conductivity of small polarons shown by the manganites above T-c. It is shown that the energy of small aligned clusters is relatively high compared with that of the fully ordered lattice which is used to show why these materials show a high degree of short-range order above T-c.
