Transport property measurement of practical coated conductor with copper stabilizer

Abstract: The transport properties of a 5-mm-wide practical PLD-GdBa 2 Cu 3 O y (GdBCO) coated conductor, which has a 100 μm thickness copper stabilizer, was evaluated. Critical currents were measured up to 600 A in magnetic fields (parallel and perpendicular to the conductor surface) up to 12 T and in a temperature range of 4.2 to 85 K. The temperature dependence of n-value and the power law decay of J c in low field were evaluated. I c anisotropy and pinning properties were also discussed. The results suggest that ran… Show more

“…Furthermore, the n exponent is field dependent with B, and this relation was considered using a curve obtained from a similar material, as done in [26]. This approach can be used for magnetic inductions in the range of 0-1T, presenting n = 20~25 at 77 K [27]. The above equations were solved by COMSOL ® software using the finite element method (FEM).…”

“…A key challenge is that, in certain configurations, they are vulnerable to delamination between the different tape layers, due to thermal and magnetic forces experienced during magnet operation [11][12][13]. REBCO tapes exhibit exceptional axial strength and can withstand up to 700 MPa of stress [14] in that orientation, however when put under a transverse tension, the tape can delaminate under 10-20 MPa of stress [15,16].…”
