Percolation conductivity of single-crystal manganite [Pr.sub.1-x][Sr.sub.x]mn[O.sub.3] in the phase-separation state
This paper presents an experimental study of the temperature dependences of the electrical resistivity, thermopower, and magnetoresistance of single-crystal manganite [Pr.sub.1 - x][Sr.sub.x]Mn[O.sub.3] (x = 0.22, 0.24). The results obtained have been analyzed in terms of the theory of hopping elect...

| description | This paper presents an experimental study of the temperature dependences of the electrical resistivity, thermopower, and magnetoresistance of single-crystal manganite [Pr.sub.1 - x][Sr.sub.x]Mn[O.sub.3] (x = 0.22, 0.24). The results obtained have been analyzed in terms of the theory of hopping electrical conductivity of manganites in the phase-separation state and the main postulates of percolation theory. In the 2-400-K interval, hopping conductivity with temperature-dependent activation energy has been observed. Near the Curie temperature, the monotonic exponential growth of electrical resistivity with decreasing temperature becomes distorted by formation of finite metallic clusters. For T ≤ 36 K, the conductivity of [Pr.sub.0.8][Sr.sub.0.22]Mn[O.sub.3] follows the Mott law. |
