Summary :

Nojima and Fujita have found a universal relation, irrespective of temperatures T, between the reduced field hH/H_ir(T) and the reduced quantity of magnetization hysteresis mΔM (T, H)/ΔM (T, H0), where H_ir is the irreversibility field and ΔM(T, H) is the hysteresis of magnetization for YBa₂Cu₃O_x and Bi₂Sr₂CaCu₂O_x films. We could explain this universal relation based on a scaling theory in a three-dimensional superconducting vortex-glass phase. The exponent ν derived by this relation coincides with that obtained by nonlinear I-V characteristics for YBa₂Cu₃O_x films.
