โœฆ Synopsis


We review the experimental and theoretical study of hysteresis losses, W,, in monolithic and isotropic type II superconductors subjected to an alternating magnetic field H,, or alternating current Z,, in the presence of a static bias magnetic field Hbias or bias current Ibias. Five situations are addressed. (i) W,, (Hbias, Ha,) vs Hbias, where Hbim is // to Ha, and Tis constant, (ii) W,, (Hbim, H,,) vs Z (iii) K, (Ibias. L) vs Ibias, (iv) Kc CL, H//l, where Hbias = H,, is along the axis of a wire, and, (v) W,, (Hbias, H,) in ribbons where H bras is tilted with respect to H,,.
