Penetration of Josephson vortices and measurement of the c-axis penetration depth in $B{i}_{2}S{r}_{2}CaC{u}_2{O}_{8+\delta }$: Interplay of Josephson coupling, surface barrier and defects

H. Enriquez, N. Bontemps, A. A. Zhukov +5

The first penetration field H_{J}(T) of Josephson vortices is measured through the onset of microwave absorption in the locked state, in slightly overdoped $\rm{Bi_{2}Sr_{2}CaCu_{2…
