Nonlinear logarithmic time decay of magnetization has been observed over a long measuring time period ({ital t}=22 h) for a single crystal of Bi{sub 2}Sr{sub 2}CaCu{sub 2}O{sub {ital x}}. At relatively low temperatures ({ital T}=12 K) linear ln({ital t}) decay of the magnetization is observed for field (=1 kG) parallel to the {ital c} axis, which can be described well by the Anderson-Kim model. However, at high temperatures ({ital T}{gt}26 K) the magnetization exhibits nonlinear logarithmic time near the irreversibility line. Possible connections between the experimental data and current theories are discussed.
