Enhanced Spin Tunneling in a Molecular Magnet Mixed with a Superconductor

We report characterization and magnetic studies of mixtures of micrometer-size ribbons of Mn acetate and micrometer-size particles of YBaCuO superconductor. Extremely narrow zero-field spin-tunneling resonance has been observed in the mixtures, pointing to the absence of the inhomogeneous dipolar br...
