Abstract

In our paper, we study the effect of hydrostatic pressure on the magnetic and insulator–metal transitions of La0.67Pb0.33Co0.1Mn0.9O2.97 manganite. The insulator–metal transition does not coincide with the magnetic transition in this ceramic. The compound undergoes the paramagnetic–ferromagnetic phase transition at Tc=260 K and the insulator–metal transition at Tp=184 K at ambient pressure. We have found that both characteristic temperatures Tc and Tp increase with increasing hydrostatic pressure with ΔTC/Δp = 11.2 K/GPa and ΔTp/Δp = 20.1 K/GPa, respectively.
