Abstract

Josephson plasma resonance has been introduced recently as a powerful tool to probe interlayer Josephson coupling in different regions of vortex phase diagram. In the pancake liquid plasma resonance frequency (omega) _p(B,T) as function of the magnetic field B was obtained previously using the high temperature expansion. We further develop this approach and derive a general relation connecting (omega) _p(B) with the density correlation function of pancake liquid. The relation provides unique opportunity to extract quantitative information on the c-axis correlations of pancake liquid in crystals with weak and strong pinning from the dependence of plasma resonance on the ab-component of magnetic field at fixed c component. We discuss c-axis correlations in crystals with weak disorder and crystals with columnar defects produced by irradiation.
