In collective pinning theory, vortex pinning energy, U, is a key parameter in describing thermally activated flux motion, but it is a function of the critical current density J c , glassy exponent l and pinning energy U 0 , under the base of GriessenΓs and our groupΓs methods of obtaining J c and l,
We calculate the tilt modulus (744 and make collective pinning estimates for a vortex lattice in magnetically coupled superconducting layers. The tilt modulus has unusual nonlocal structure which leads to peculiar pinning behavior. Namely, under the certain conditions for the pinning strength and th
