Abstract
The possibility of flux pinning by different defects in the volume of high-T(c) superconductors is investigated. The elementary pinning pote ntial, U(P), and the pinning force, f(P), of point defects (vacancies) , one dimensional defects (dislocations), two-dimensional defects (twi n and low angle boundaries) and three dimensional defects (pores, prec ipitates, etc.) are estimated. The effectivity of the different defect s acting as pinning centres is examined.
