    We have demonstrated numerically that a waveguide formed by the interface of a metal and uniformly magnetized two-dimensional photonic crystal fabricated from a transparent dielectric magneto-optic (MO) material possesses a one-way frequency range where only a forward propagating surface plasmon polariton (SPP) mode is allowed to propagate. In contrast to an analogous waveguide proposed by Yu1 the non-reciprocity at the interface is introduced by the MO properties of the photonic crystal material, namely Bismuth Iron Garnet (BIG, Bi3Fe5O12), a ferrimagnetic oxide which may be easily magnetically saturated by fields of the order of tens of mT. Therefore, this configuration allows to achieve sizable one-way bandwidth by using realistic values of the external magnetic field which makes such a waveguide favorable for design of diode-like elements in optical integrated circuits.
