Measurement Method: Vibrating sample magnetometer
"The magnetic measurements were made by means of a vibrating sample magnetometer for both orientations of magnetic field, i.e. perpendicular... and parallel... to the tape plane. Constant magnetic sweep rates were used for the magnetization measurements. Because the magnetic moment from such a thin tape is small, we have used 30 pieces of the same tape with lengths of 5 mm, which were tightly stuck together. The small thickness of 45 µm in comparison with the tape length of 5 mm means that for both orientations of magnetic field the magnetic moment is determined by the current parallel to the tape plane (i.e. almost parallel to the a-b plane)... the irreversibility field... has been taken as the field at which the critical current reaches 250 A cm^-2."
