(a) Zero-field heat capacity of \({\text {Pr}}_2 {\text {Co}}_{0.86} {\text {Si}}_{2.88}\), its non-magnetic counterpart \({\text {La}}_2 {\text {Co}}_{0.99} {\text {Si}}_{2.99}\), along with the magnetic component in heat capacity of the former (left panel) and magnetic entropy (right panel) as a function of temperature. Inset shows the expanded view of magnetic contribution for a limited range of temperature. (b) Heat capacity data in the form of C/T as a function of \(T^2\). Inset shows the expanded view in the low temperature region.
