N2 - We present near-infrared spectroscopic observations of the AM Herculis systems EF Eridani and BL Hydri over the wavelength range 0.9 to 2.5 μm. During these observations, broad and resolvable cyclotron emission harmonics were visible near 1.05, 1.30, 1.70 and 2.20 μm in EF Eridani, and near 1.25, 1.60 and 2.20 μm in BL Hydri. We interpret these features as arising from cyclotron emission regions located near the polar caps of the white dwarf of magnetic field strength B = 23 MG in BL Hydri, and from two separate cyclotron emission regions of field strengths B = 16.5 and 21 MG in EF Eridani.
