Transport properties of Sr[0.75-x]Ca[x]Y[0.25]Со[0.25]Мn[0.75-x]O[3-δ], 0 ≤ X ≤ 0.6

Condensed matter physics

A structure and a conductivity of novel Sr[0.75-x]Ca[x]Y[0.25]Со[0.25]Мn[0.75-x]O[3-δ] complex oxides, 0 ≤ X ≤ 0.6, have been studied, in the temperature range of 4.2 К to 300 К carrier transport mechanisms for samples were investigated in d-c and a-c (20Hz - 1MHz) fields.
