The critical current density J , of the (YBa,Cu307),/(PrBa,Cu307)8 (YBCO),/(PrBCO),] superlattice as a function of the angle ff between thc direction of the magnetic field and the c-axis is measured in several magnetic fields at T = 55.8 K. Experimental results show that the angular dependence of J , can be well scaled by a 2D model, i.e., only the perpendicular field component is relevant. The pinning mechanism in this film is discussed.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
