In the present work specific heat measurements have been carried out for the Mn-substituted compounds Y0.95Pr0.05Ba 2(Cu1-xMnx)3Oy (0 x 2%) using the semi adiabatic heat pulse method. Resistivity measurements indicate that resistivity increases with Mn concentration. In the present setup, we could get absolute accuracy in specific heat of about 0.5% for samples of about few hundred mg. The present results show that specific heat jump of 3.8 J/mol K, was observed only for pure Y-123 sample. However no jump was observed in other samples.
