|Title:||The paramagnetic meissner effect in nd2-xcexcuoy superconductors at 40 g and flux trapping|

|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-T-c regions embedded inside the higher-T-c layers of superconducting (SC) grains or portions. These shell-like varying-T-c 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.|
