摘要：

A paramagnetic moment (Wohlleben effect) is observed in superconducting HoBa2Cu3O7-y films both in field cooling and zero field cooling measurements. This effect is explained by a model of a negative critical Josephson current in the weak-link loops in the films.© 1995 American Institute of Physics.
