Phenomenological model of high-Tc superconductivity: a MCS model

Abstract

Since the introduction of a MCS (Magnetic Coupling between Stripes) phenomenological model [cond-mat/9902355, to be published in J. Superconductivity] for hole-doped cuprates many new experimental data have been presented in the literature as evidence in support of the MCS model. We consider here recent data and the MCS model which is based upon experimental facts, namely, the presence of (i) stripes; (ii) spin fluctuations, and (iii) two order parameters (for pairing and for long-phase coherence) in hole-doped cuprates. We discuss also the superconductivity in the s-wave Nd 2-x Ce x CuO 4 cuprate.

“…Earlier, we proposed a magnetic coupling between stripes (MCS) model assuming that the Cooper pairs are formed along charge stripes, and the phase coherence is established due to magnetic coupling between SC stripes [99]. From the present work, the general idea of the MCS model is correct, however the more precise name of the model of SC in cuprates should be the magnetic coupling between striped CuO 2 planes.…”
