Abstract

Abstract Josephson plasma resonance of under-doped Bi 2Sr 2CaCu 2O 8+ δ single crystals in magnetic fields parallel to the ab-plane has been studied at microwave frequencies ν between 10 and 52 GHz. Two resonance lines are discovered with distinctly different characters as functions of different physical parameters such as magnetic fields, microwave frequencies, temperatures, etc. Those two resonances behave entirely differently from the ones for H∥c and are attributed to the mixed resonance plasma modes with collective motion of the Josephson vortices.
