Abstract
We have studied the hysteretic loss and the shielding capability of st ructured YBa2Cu3P7 thin films in transverse ac magnetic fields between 1 mu T and 1 mT. The normalized value of the ne susceptibility as a f unction of reduced ac field h/h(m), (h(m) being the ac field at the di ssipation maximum) shows no temperature dependence and is independent of the geometry. The ac field dependence can be well understood with r ecently published theories for thin superconductors in transverse geom etry by Mikheenko and Kuzovlev (disk) and by Brandt (strip).
