| Critical Temperature (K) |
| 86 |
Measurement Method: Vibrating sample magnetometer
"The sample for magnetization measurements was a plane with thickness about 24 µm along the c-axis and an area about 1.4 mm x 8 mm parallel to the a-b plane... Magnetization was measured using a vibrating sample magnetometer... In this apparatus, maximum magnetic field 6 T is applicable, and temperature can be changed from 4.2 K to room temperature within the accuracy of 0.3 K. ...the magnetic field was applied perpendicular to the a-b plane of the crystal. ... Applying the Bean's critical state model to this result, we can calculate J
