摘要：

EPR studies show axial Cr3+ centres in Cr-doped ferroelectric PbTiO3 ceramic after heat treatment in hydrogen atmosphere. The fine-structure splitting at room temperature was interpreted on the basis of the Newman superposition model. The temperature dependence of the fine-structure splitting has been measured and discussed. A hopping model was introduced to interpret these results. © 1990.
