Abstract

The mechanical behaviors of flux pinning in GdxY1−xBa2Cu3Oy with various concentration of Gd were studied comparatively by means of a vibrating reed technique. Both the internal friction and the modulus increased with enhanced flux pinning due to the increasing of Gd content in GdxY1−xBa2Cu3Oy. It was in accordance with the results of the magnetic hysteresis measurements using a vibrating sample magnetometer. These results indicated that the substitution of magnetic rare-earth ions is a practicable method for improving the flux pinning in high Tc superconductor and the mechanical measurement of flux pinning as a judgement for the superconductivity of sample was proved.
