Description
Recent orthorhombic-tetragonal (O-T) phase equilibria predicted by Khachaturyan and Morris have been observed experimentally in YBa2Cu/sub 3-//sub x/Fe/sub x/O7 (0.01≤x≤0.2) by Moessbauer techniques. The relative proportions of O and T phases are found to be functions of Fe concentration. The T phase grows from, and coexists with, the O phase as x increases. A nonzero fraction of T phase persists down to the smallest values of x. A model is presented to interpret the structural aspects of the O-T transition
