Description electrical and magnetic properties of La(1-x)Ca(x)Mn(0.7)Co(0.3)O(3) (0.1 less than or equal toxless than or equal to 0.5) have been investigated. From the magnetic measurement it is evident that high spin Co(3+) transforms to low spin Co(3+) (diamagnetic) at low temperatures which influences its magnetic and transport properties. Change in spin state of Co(3+) leads to change in the magnetic structure. The experimental resistivity data are examined using the small-polaron transport model and it finds a good theoretical fit.
