Analog of Magnetoelectric Effect in High-Tc Granular Superconductors
We propose the existence of an electric-field induced nonlinear magnetization
in a weakly coupled granular superconductor due to time-parity violation. As
the field increases the induced magnetization passes from para- to dia-magnetic
behavior. We discuss conditions under which this effect could be experimentally
measured in high-temperature superconductors.Comment: REVTEX (epsf style), 1 PS figure; to appear in Europhysics Letter
