摘要：

A single crystal of has been exposed to fast neutron irradiation up to a fluence of D.c. magnetization measurements made prior to and following irradiation show significant enhancements of irreversibility in the magnetization loops and a shift of the drreversibilityn line to much higher fields and temperatures. This provides evidence for the absence of phase transitions in the flux line lattice and the predominance of depinning phenomena at high fields and temperatures. © 1990 IOP Publishing Ltd.
