We defined Ic(sf) as the threshold current, Ic,B, at which the perpendicular component of the local magnetic flux density, measured at any point on the surface of a high-temperature superconducting tape, abruptly crosses over from a non-linear to a linear dependence with increasing transport current. This effect results from the current distribution across the tape width p","authors_text":"A. E. Pantoja, Evgeny F. Talantsev, Jeffery L. Tallon, Justin Brooks, Nick M. Strickland, Rod A.
