From: Oxypnictide SmFeAs(O,F) superconductor: a candidate for high–field magnet applications
In-field critical current density (Jc) performance of SmFeAs(O,F) thin film at 4.2 K.
(a) Field dependence of Jc measured at 4.2 K up to 45 T for both crystallographic directions and (b) the corresponding exponent n values.A crossover from extrinsic to intrinsic pinning is shown by the arrow. (c) Scaling behaviour of the field dependent Jc. (d) The pinning force density Fp for both crystallographic directions at 4.2 K.
