Abstract

In this paper, we have studied tunneling effect of the spin-2 Bose condensate driven by external magnetic field. We find that the population transfers among spin-0 and spin-1, spin-0 and spin-2 exhibit the step structure under the external cosinusoidal magnetic field respectively, but there do not exist step structure among spin-1 and spin-2. The tunneling current among spin-1 and spin-2 may exhibit periodically oscillation behavior, but among spin-0 and spin-1, spin-0 and spin-2, the tunneling currents exhibit irregular oscillation behavior.
