Irreversibility curve and dissipative losses in YBaCO films

Abstract

The susceptibility of polycrystalline and epitaxial YBCO films in weak exciting magnetic fields Hac = (0.1–1000) mOe is investigated by using the inductive technique. The behavior of their irreversibility curves (1-Tm/Tc) and the peak of dissipative losses is studied. Two characteristic fields H1* and H2* are observed for which the curves (1-Tm/Tc)(Hac) and χm″(Hac) change their slope. It is shown that the exponent in the equation (1-Tm/Tc)= αHacq depends on the type of weak bonds formed in the film during its growth.
