摘要：
We measured the magnetic relaxation in a Bi2Sr2CaCu2Ox single crystal at a wide range of temperatures (6 25 K) and field strengths (100 4000 G). We found that the relaxation rate (dM/d lnt) is highly temperature and field dependent. By expanding Kims model, we developed an expression for dM/d lnt as a function of field that we used to interpret the rise and fall of the magnetic relaxation in both the H<H* and H>H* regions. © 1990 The American Physical Society.
