Abstract: Magnetic Relexation was studied at a wide range of temperatures and magnetic
fields for a Ag-sheathed Bi-based superconducting tape with highly-c-axis orientation
and high critical current density (J, > lo4 A/cm2 at 77 K and 0 T). Under certain
conditions, it is found that the magnetization data varies nonlinearly with In(t) for
entire period of time (1 > lo4 s). The curves can be divided into two relaxation rate
(dM/dln(t)) md�ifferent period of time. It was observed that the lower the temperature
is, the higher the magnetic field needs to bend a logarithmic line into a curve with
two different relaxation rate (dM/dln(t)) in different region of time. The diagram of
temperature and magnetic field was obtained from the experiment.
