Abstract
The paramagnetic Meissner effect (PME) has been observed in Nd2-xCexCuOy superconductors at 40 G. The origin of the effect has been considered on the basis of the local oxygen variation which implies non-superconducting or lower-Tc regions embedded inside the higher-Tc layers of superconducting (SC) grains or portions. These shell-like varying-Tc SC layers in turn apparently create 'cumulatively compressed flux trapping' and hence the PME. The exhibition of PME seemingly depends on the type of defect as well as their density.
