Abstract

The magnetization reversal loops of YBa2Cu3O \(_{{7 - x}}\) superconductor specimens with complex periodic defective structures with different degree of disorder are calculated by using the Monte Carlo method. A negative effect of local disorder on the magnetization reversal loop width and the residual magnetization of the specimens is demonstrated. It is shown that the main mechanism of loss in magnetic properties consists in the formation of channels for the exit of free vortices from a specimen, but the distributions with long distances between neighboring macrodefects resist disordering better.
