The magnetoresistance of the heavy fermion compound CeInCu₂ has been measured at both ambient and hydrostatic pressures up to 2 GPa. It is found that the high pressure induces positive magnetoresistance, which is characteristic of the Kondo coherent state, associated with the enhancement of the Kondo temperature. The result is discussed briefly on the basis of the theoretical model by Kawakami and Okiji.
