(a) Zero field heat capacity of Pr₂Ni_0.95Si_2.95, La₂NiSi₃, magnetic contribution of heat capacity (left panel) and magnetic entropy (right panel) as a function of temperature. Inset shows expanded low temperature region of heat capacity for Pr₂Ni_0.95Si_2.95. (b) Heat capacity data is fitted to Debye model according to Eq. 4.
