  We report the magnetic, thermodynamic, and transport properties of a heavy
fermion compound CeNiGe2. This compound undergoes two antiferromagnetic
transitions around 4.1 and 3 K. It is observed in heat capacity that as
magnetic field is increased to ~ 1 T, the two peak merge into a single peak
around 3 K. However this peak is not suppressed under the application of
magnetic field. Instead a new feature develops at 3.6 K above 1 T. The magnetic
field induced new feature is investigated through entropy evolution, magnetic
Gruneisen parameter and resistivity studies. These studies emphasis the fact
that partial magnetic frustration due to field induced spin fluctuation is
responsible for this observed feature. This partially frustrated regime
develops a new antiferromagnetically ordered phase at high fields. In this
compound magnetic field induced QCP is absent implying that the behavior of
CeNiGe2 is not in accordance to Doniach model proposed for heavy fermions
compounds.
