| Research Abstract |
By observing the magnetizations and ac losses of REBa Cu O 2 3 7-x （RE:Rare Earth, Y, Gd and so on, REBCO）superconducting tapes at 4.2 K to 77 K, which are developed as next generation superconducting wires, with a saddle-shaped pick-up coil, it was shown that the critical currents, magnetizations and ac losses of REBCO superconducting tapes are scaled with temperature. That brings us the predictability of the ac loss properties of REBCO superconducting tapes at any temperature.
