摘要：

In this work, we report on measurements of magnetization with time [M(t)] around the pinned layer loop in spin-valve materials. These time-dependent effects are manifest via changes in M(t) in constant field (H) and via variations in the apparent coercivity with the sweep-rate of the applied field. The changes in the apparent coercivity on the pinned layer loop differ for the magnetizing and demagnetizing branches as does the form of M(t) data. (C) 2000 American Institute of Physics.
