Abstract :
The magnetization loss of the coated conductor with metal substrate is not the same with that of the coated conductor without metal substrate. Effects of the substrate on the AC loss have not been analyzed yet. In the paper, we estimated the magnetization loss in the YBCO coated conductor with metal substrate, which was exposed to the external magnetic field by using numerical calculation. The effects of magnetic property, electric property and thickness of the substrate on the AC loss of coated conductor were considered in this paper. According to the results of calculation, the existence of substrate decreased the AC loss in the coated conductor up to 39.2% at 5 mT but it increased the AC loss up to 3.7% at 100 mT.
