| Popis: | The structural, electrical, and magnetic properties of La0.67Sr0.33Mn1−xCrxO3 (0 ≤ x ≤ 0.10) manganites have been studied by substitution of antiferromagnetic trivalent Cr ion at Mn-site. Systematic efforts have been carried out to understand the electrical resistivity behavior in the ferromagnetic metallic and paramagnetic semi-conducting phases of Cr substituted La0.67Sr0.33Mn1−xCrxO3 manganites. Polycrystalline samples show a resistivity minimum at a temperature (Tmin) of |
