The magnetic and transport properties of the Cr-doped manganites La 0.46 Sr 0.54 Mn 1− y
Cr y O 3 (0≤ y≤ 0.08) with the A-type antiferromagnetic structure were investigated. Upon …

Giant magnetoresistance, and spin‐, charge‐, and orbital‐ordering are some of the
properties displayed by manganates that make these materials of interest in magnetic …

The effects of partial substitution of manganese by iron on the physical properties of Pr 0.6
Ca 0.1 Sr 0.3 Mn 1− x Fe x O 3 (0⩽ x⩽ 0.075) were investigated experimentally. Our …

We have explored the possibility of double-exchange interaction between ions of different
elements by studying a series of LaMn 1− x Cr x O 3 (0.1<~ x<~ 0. 7) perovskites, with the …

Most manganites exhibiting colossal magnetoresistant properties are structurally very
simple. They are based on a perosvskite structure with the general formula. The electric and …

Giant magnetoresistance (GMR)—the phenomenon whereby a magnetic field can
dramatically alter the electrical resistance of a material—and related properties of the rare …

Giant magnetoresistance and related properties such as charge-ordering in manganates
have been investigated with great vigor in the last two years. The manganates have turned …

Mn-doped CuCrO 2 polycrystalline semiconductors were synthesized by the sol–gel
method. The valence state of the Mn ions in the CuCr 1− x Mn x O 2 samples was identified …

We report measurements of the magnetic and electrical properties of sintered manganites of
the form. We find that the peak in the conductivity moves rapidly to lower temperatures as the …

Abstract CuCrO 2 and CuCrO 2: Mn thin films were prepared on sapphire substrates by
chemical solution deposition method. The effects of the annealing temperatures and Mn …
