  Field variation of heat capacity at fixed temperatures is investigated to
identify the origin of the field induced first order phase transition in
polycrystalline Ce(Fe$_{0.094}$Al$_{0.04}$)$_2$ sample. The heat capacity at
4.5K and 3.5K shows hysteresis in different field cycles and the virgin curve
stays outside the envelope curve. This is analogous to the magnetization and
magneto-resistance behavior observed in this system, where the amount of
hysteresis, and the magnitude of zero-field irreversibility are attributed to
the degree of supercooling/superheating, and the extent of kinetic arrest of
the reverse transition from ferro- to antifrromagnetic state in field reducing
cycle respectively. However, contrary to the magnetization and
magneto-resistance, in heat capacity both these features have decreased with
reducing temperature signifying the importance of structural contribution.
