Current driven pinning strength in the vortex lattice of Nb3Sn aided by a small oscillating magnetic field

By the application of a small oscillating magnetic field parallel to the main magnetic field and perpendicular to the transport current, we were able to generate a voltage dip in the I-V curves of Nb\(_3\)Sn similar to the peak-effect pattern observed in earlier resistivity measurements. The pattern...

Description
Summary:By the application of a small oscillating magnetic field parallel to the main magnetic field and perpendicular to the transport current, we were able to generate a voltage dip in the I-V curves of Nb\(_3\)Sn similar to the peak-effect pattern observed in earlier resistivity measurements. The pattern was history dependent and exhibited a memory effect. In addition we observed in the I-V curves for a high shaking-field amplitude a step feature of unknown origin.
