Abstract
An induced heat instability proposed to explain the difference between microwave properties of YBCO single crystals and thin films at temperatures just below Tc. Extended strain fields near out-of-plane edge dislocations are initial discontinuities for the instability development. We have shown theoretically and have confirmed experimentally that a single dislocation can not have a strong effect on the microwave surface resistance Rs. Dislocation arrays, which were observed experimentally, can induce the thermal instability if edge dislocations in the arrays are spaced closer than the heat relaxation length. Ordered dislocation structures provide much higher local temperature perturbation than randomly distributed dislocations.
