摘要: AC transport current losses in HoBaCuO-123 tape-shaped coated conductors with ferro-magnetic Ni-alloy substrates were measured as a function of an external DC magnetic field. Influence ferromagnetism the on was investigated. The experimental results compared theoretical models given by Norris equations, and showed significant influence substrates, when not magnetically saturated However, saturated, loss characteristics similar to those non-magnetic substrates. experiments also that strongly dependent direction field wide face tape.
