Predicted electric field induced surface magnetization of vortex phase of superconductors

Abstract

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.

Scientific instrument for creation of effective Cooper pair mass spectroscopy

“…After the buffer we have a difference amplifier with frequency dependence of the amplification coinciding with the last inverting amplifier Y ∆ = Y IA . In such a way the total amplification is given by the product Set-up for study of surface magnetization of the vortex phase of superconductors induced by AC electric field applied to the surface [2]. Magnetic field B B c2 (T ) is created by a Nd permanent magnet.…”

“…The purpose of the present study is to evaluate experimental efforts necessary for the creation of Cooper pair mass spectroscopy: equipment, samples, consumptives, and perspectives for further development. A review of present status of the problem together with detailed theory is given in our recent papers [1,2] and references therein ( [3,4,5,6,7,8,9,10,11,12,13,14,15,16] and so on). In the next Sec.…”
