  In this letter we introduce a new soft ferromagnetic compound, i.e. CeMnNi4,
which exhibits a large moment (~4.95mu_B/Mn) and high degree of spin
polarization. The system has a ferromagnetic transition temperature of 148K.
Isothermal magnetization measurements at 5K reveal that the material is a soft
ferromagnet with a magnetization saturating at about 500Oe and a coercive field
of < 5 Oe. We determine the transport spin polarization of this material from
Point Contact Andreev Reflection measurements to be 66% thereby making this
material potentially important for spintronic applications.
