Abstract

The dependence of the Josephson plasma frequency ωp in Bi2Sr2CaCu2O8 on a tilted field H is reported. Measurements over a large range of B and tilt angle θ allow a detailed comparison with a recent calculation by Koshelev. With a slight modification of the model, close agreement is obtained. From the fits, we find values for the in-plane correlation length and the zero-field critical current density Jc0 (4600 A/cm2 at 30 K). An analogy to Bragg diffraction is described, as well as a picture for the fractional-exponent behavior of ωp vs. H.
