抄録

Small phase oscillation modes of a triangular Josephson vortex lattice in a stack of intrinsic Josephson junctions are clarified. The eigen-frequency of the lowest excitation mode, ω₁, is less than the zero-field plasma frequency, ω_pl, and is a decreasing function of the magnetic field H. The eigen-frequencies ω_n with n≥2 is located above ω_pl and increases with increasing H. This result is consistent with the field dependence of the Josephson plasma resonance observed in Bi-2212 and YBCO.
