Modeling of Magnetization Loss in HTS Tape Exposed to All Magnetic Field Directions

In this paper, we suggest a new magnetization loss model for all magnetic field directions. We measured three types of HTS tapes, two different critical current Bi2223/Ag tapes, and an YBCO tape to compare the measurement with the magnetization loss model. Our new model is based on the measured magnetization losses, because the loss is affected by the intrinsic critical current distribution and the cross-section. The studied conditions of the base magnetization losses are: the magnetic field applied perpendicular to the tape axis and perpendicular to the tape face, perpendicular to the tape axis and parallel to the tape face, and parallel to the tape axis. This model enables us to describe magnetization losses in response to a change in the amplitude of the magnetic field, the angle of the tape axis, and the angle of the tape face.
