Abstract

We investigated uni-axial tensile stress dependence of AC losses (transport current, magnetization and total losses) in HTS coated conductor with magnetic Ni-alloy substrate. The AC loss characteristics are studied by relating to tensile stress dependence of critical currents of the conductor. Experimental results showed that the loss characteristics were different whether the critical current recovered the original value after the release of the stress or not. Dependence of AC loss characteristics on magnetic property of the substrate is also studied.
