Simulations of local field inhomogeneities of magnetic tracks and their impact on the magnetization of HTSs with defects

Abstract

Using the Monte Carlo method, the full and partial magnetization loops of a YBCO superconductor have been studied. The partial loops simulated field inhomogeneities occurring on magnetic tracks in levitation systems. The influence of temperature and defect concentration on the shape and area of the full and partial hysteretic curves has been studied. The highest considered defect concentration provided the least partial curve area which meant less hysteresis energy losses and greater levitation stability.
