In our paper we report on magnetic properties of La0.90Ag0.10(CoxMn1-x)O3 ferromagnetic ceramics (x = 0.00 and0.03) which were studied in pressures up to 0.9 GPa. Magnetic transition at the Curie temperature TC is accompanied with metal insulator transition with a maximum at T* which is shifted to lower temperature with applied magnetic field. The Curie temperature is decreasing with substitution of Co for Mn and is ranging from 178 K to 126.5 K. Hydrostatic pressure increases TC for sample with x = 0.03 nearly linearly with the pressure coefficient dTc/dp = 5.7 K/GPa. Hysteresis loop is affected marginally; µs increases and Hc decreases with pressure.
