Pressure effect on magnetic and insulator-metal transition of La0.67Pb0.33Mn0.9Co0.1O2.97 ceramic
In our paper, we study the effect of hydrostatic pressure on the magnetic and insulator-metal transitions of La0.67Pb0.33Mn0.9Co0.1O2.97 manganite. The insulator-metal transition does not...

Metal–Insulator Transition in CaCu3Fe4O12
We study structurally-triggered metal–insulator transition in CaCu3Fe4O12 (DMFT). The ferrimagnetic insulating phase is essentially the same within both approaches. While LDA+U describes the metal–insu...

Influence of the structure on electric and magnetic properties of La0.8Na0.2Mn1-xCoxO3 perovskites
The influence of the cobalt substitution for manganese ions in the mixed valence perovskites La0.8Na0.2Mn1-xCoxO3 (0?x?0.2) was investigated by X-ray, electric transport and magnetic measurements. The study carried out on sintered polycrysta...

Collapse of magnetic moment drives the Mott transition in MnO
We report results for the classic correlated insulator MnO that reproduce a simultaneous moment collapse, volume collapse and metallization transition near the observed critical pressure, and identify the mechanism as colla...

The low-temperature phase separation in Pr0.5Ca0.5CoO3.
below 75 K, the sample undergoes an incomplete transition to a ferromagnetic phase of enhanced metallic character. Residual paramagnetic regions exhibit at 30 K a metal-insulator transition, which is inte...

Metal-insulator transition and the Pr3+/Pr4.+ valence shift in (Pr1-yYy)0.7Ca0.3CoO3.
The magnetic, electric, and thermal properties of the (Ln1-yYy0.7Ca0.3CoO3 perovskites (Ln=Pr,Nd) were investigated down to very low temperatures. The main attention was given to a peculiar metal-insulator (M-I) transit...
