Abstract
Magnetic properties of bulk melt-textured YBa2Cu3O7 prepared in a sola r furnace were investigated. The material obtained demonstrates high c ritical Current density of the order of 10(5) A/cm(2) in the field of a 1 T at 50 K. The effective activation energy for flux creep was calc ulated using Maley's approach and fits the universal relation: U-eff=U (0)G(T)(J/J(c))(-n), where n=3/2, which agrees with the result predict ed by the collective flux creep theory.
