摘要: The magnetic and proton energy Ep dependence of the pinning U critical current density have been investigated in polycrystalline Gd 1-x Pr x Ba 2 Cu 3 O 7-δ samples irradiated by protons, where 0 < 0.15. resistivity measurements field H up to 10 kOe indicate that β exponent eff is independent Pr-doping value for unirradiated samples, but rises as irradiating protons increases. slope a oc E α(H) p versus x. In addition, some effects irradiation compared with those creating effective centers. I-V fields 15 increases all remains constant values, except special case when = 0.1.
