From the second magnetization peak to peak effect. A study of superconducting properties in Nb films and MgB2 bulk samples

Dimosthenis Stamopoulos, Athanasios Speliotis, Dimitris Niarchos

We report on magnetic and magnetoresistance measurements in two categories of superconducting Nb films grown via magnetron sputtering and MgB2 bulk samples. In the first category,…
