Enhancement of the magnetoresistive effect in nanocomposites based on manganite La0.67Sr0.33MnO3 and magnetite Fe3O4
Abstract
<p>The effect of a magnetite Fe<sub>3</sub>O<sub>4</sub> nanopowder in a nanocomposite with manganite La<sub>0. 67</sub>Sr<sub>0. 33</sub>MnO<sub>3</sub> on its magnetoresistive effect and conductivity is studied. The addition of a magnetite nanopowder to the initial material leads to a substantial (twofold) increase in the low-field magnetoresistive effect. The low-field magnetoresistive effect in substituted lanthanum manganite nanopowders is based on spin-dependent electron tunneling through grain boundaries. The transport mechanisms in such systems are analyzed, and noise spectroscopy is also used for this purpose.</p>
