Query: Predicted electric field induced surface magnetization of vortex phase
  of superconductors   We predict a new effect in condensed matter surface magnetization of the
vortex phase of a superconductor induced by electric field. The magnetized
superconductor should be one of the plates of a plane capacitor on which a
voltage has to be applied. Applying alternating voltage to the capacitor,
electrostatic induction leads to oscillations of the magnetic moment which has
to be measured by electromotive force inducted in a detector coil. The derived
explicit formula for the magnetization contains the effective mass of Cooper
pairs and a systematic investigation of the predicted magnetization will lead
to a creation of an effective Cooper pair mass spectroscopy. For cleaved
superconductors this effective mass is a property of the bulk material.
