Description

We have searched for anomalous internal magnetic fields in high Tc materials which are predicted to occur in anyon and flux phase models of superconductivity. The magnitude, anisotropy and temperature dependence of the observed fields in c-axis oriented samples of sintered YBa2CuO3O7 and of thick-film Bi2Sr2CaCu2O8 are consistent with a conventional nuclear dipolar origin. An upper limit of < or approx.0.08 mT is set for any anomalous magnetic fields along the c-axis at μ+ sites in bulk CuO2 superconductors. (orig.)
