Abstract

In our paper, we study the effect of hydrostatic pressure on the magnetic and insulator-metal transitions of La 0.67Pb 0.33Co 0.1Mn 0.9O 2.97 manganite. The insulator-metal transition does not coincide with the magnetic transition in this ceramic. The compound undergoes the paramagnetic-ferromagnetic phase transition at T C=260 K and the insulator-metal transition at T p=184K at ambient pressure. We have found that both characteristic temperatures T C and T p increase with increasing hydrostatic pressure with ΔT C/Δp=11.2K/GPa and ΔT p/Δp=20.1K/GPa, respectively.
