✦ Synopsis

The magnetization loss in a perpendicular external magnetic field is main AC loss of YBCO coated conductor for AC power applications. One of solutions for decreasing the magnetization loss is to make striations on it and to transpose the striated coated conductors. We measured the magnetization losses of several samples made by striated and transposed YBCO coated conductors in external magnetic field with an inclined angle for wide face of YBCO coated conductor. We compared the measured magnetization loss at an arbitrary direction in the magnetic field with those measured in a perpendicular magnetic field at the same value of perpendicular component of the external magnetic field. The results agree well with each other in all samples. This means that the magnetization loss in any directional applied magnetic field can be estimated by using only the perpendicular loss data.

The YBCO layer of coated conductors is usually covered by a protective layer of metal such as silver. From the viewpoint of stability and quench protection, a thicker protective layer is preferable, but an increase in the thickness of the protective layer might result in an increase in the AC loss.
