It is shown that charge transport in substituted manganites (La1/3S2/3)(0.67)Ba0.33-xSrxMnO3 (x = 0.0: 0.1: 0.2 and 0.33) is through polarons which are formed through electron-phonon interaction whose strength determines the mobility of the charge ca
Effect of Cr substitution on transport and magnetic ordering in Nd0.50Sr0.50Mn1-xCrxO3(0.001⩽x⩽0.20)

Chromium substitution in the charge ordered compound Nd 0.50 Sr 0.50 MnO 3 has been studied within the concentration range of 20% to examine its effect on magnetic and transport properties. It is found that the system comprises of three distinct magn

We have synthesized La(0.67)Ca(0.33)MnO(3) (LCMO):xZnO (0 less than or equal to x less than or equal to 0.475) composites through a citrate gel route and have characterized them for magnetic and magnetotransport properties. In lower concentrations (x

The transport and magnetic studies of a series of compounds having the general formula La0.7Ca0.3Mn1−xCoxO3 (0.1 ≤ x < 0.9) have shown that Co3+ can exist both in high spin and low spin states (diamagnetic state). This is found to affect greatly

The composites of La2/3Ca1/3MnO3:xSiO2 (0less-than-or-equals, slantxless-than-or-equals, slant0.40) have been synthesized by sol–gel technique to derive homogeneous nanocomposites. Si4+ by virtue of its strong preference for tetrahedral site does n
