Vs. Nikolayev, TWIN SPACING AND THE STRUCTURAL PHASE-TRANSITIONS IN RBA2CU3O7-DELTA HIGH-TC SUPERCONDUCTORS, Physical review. B, Condensed matter, 50(6), 1994, pp. 4163-4167
The properties of the structural twins in RBa2Cu3O7-delta compounds ar
e investigated in a wide range of temperatures in the framework of the
suggested model. The dependence of the size of the twins versus tempe
rature is considered. The temperature interval of the sharp increase o
f twin size with increase of the temperature is found.
