Abstract
We investigate the hysteresis curve of a 2D Random Bond Ising Model (R BIM) with anti- (AF) and ferromagnetic (F) couplings at concentration of 50% each. The hysteresis curves show magnetization jumps (first ord er transitions) at well defined magnetic fields indicating topological blocking effects caused by frustration domains in the system.
