  We study propagation of transverse-magnetic (TM) electromagnetic waves in the
bulk and at the surface of magnetized epsilon-near-zero (ENZ) medium in a Voigt
configuration. We reveal that in a certain range of material parameters novel
regimes of wave propagation emerge: we show that the transparency of the medium
can be altered with the magnetization leading either to magnetically induced
Hall opacity or Hall transparency of the ENZ. In our theoretical study, we
demonstrate that surface waves at the interface between either a transparent or
an opaque Hall medium and a homogeneous medium may, under certain conditions,
be predominantly one-way. Moreover, we predict that one-way photonic surface
states may exist at the interface of an opaque Hall ENZ and a regular metal,
giving rise to a possibility for backscattering immune wave propagation and
isolation.
