A new model of high-Tc superconductivity (HTSC) has been developed by us which we find is able to explain almost all the HTSC properties, like high Tc, origin and nature of NSPG (normal state pseudogap), anomalous superconducting state (SS) energy gap (SSEG) properties, absence of NMR spin relaxation rate coherence peak, existence of NSPG below Tc, nature of high-Tc magnetic superconductivity, external magnetic field (H) dependence of the NSPG formation temperature T*, etc. The coexistence of NSPG and SS BCS energy gap (EG), below TC, has been predicted by the model before its experimental observation, showing that the observed SSEG is a superposition of NSPG and SS BCS EG. In this paper we show that our model, called paired cluster (PC) model, is able to explain the pseudogap critical concentration, vortex core pseudogap and possible stripe phase in high-Tc superconductors.
