Abstract
This publication deals with the current controversy concerning flux creep or glass behavior in high-T c superconducting single crystals. It is shown that the flux creep picture is merely a phenomenological approach to the glass behavior for relatively short times and low temperatures. Glassy effects are predicted for temperatures between 70% and 95% T c and magnetic field in the range of 300 G to 2000 G. The glass concept can be understood as a generalization of the traditional flux creep picture.KeywordsSpin GlassGlass ModelAmerican Physical SocietyFlux CreepGlass BehaviorThese keywords were added by machine and not by the authors.
