dc.descriptionStructural, electrical and magnetic measurements of 115 single crystals of PrIn$_5$ are reported. It has a tetragonal structure and has slightly lower cell volume than its isomorphic counter part CeCoIn_5. The resistivity saturates for T\geq 10K. Analysis of the resistivity for 10K<T< 60K indicates a regular fermi liquid behavior. It does not exhibit superconductivity down to T\sim 1K. The magnetic susceptibility analysis yielded the moment to be 4.00μ_B indicating that the magnetism of PrCoIn_5 is dominated by Pr^{3+} free ions with some admixture of the magnetic moment of the Co sublattice. The paramagnetic Curie temperature θ\sim-40K. At low temperatures the susceptibility follows a broad maximum around T_N \sim 14.5K, and increases as the temperature is lowered. The disappearance of superconductivity for T>1K is attributed to chemical pressure effects and magnetic pair breaking.
