Some experiments on flux pinning in Pb doped Bi-Sr-Ca-Cu-O system

In order to investigate the mechanism of energy dissipation by irreversible motion of fluxoids, we performed two different types of experiments; the oscillating-pendulum in magnetic field and the magnetic hysteresis including both major and minor loops. Results obtained for Pb-doped Bi-Sr-Ca-Cu-O sy...

Zusammenfassung:In order to investigate the mechanism of energy dissipation by irreversible motion of fluxoids, we performed two different types of experiments; the oscillating-pendulum in magnetic field and the magnetic hysteresis including both major and minor loops. Results obtained for Pb-doped Bi-Sr-Ca-Cu-O system at 77 K are presented and some preliminary discussions are made.
