Spin-dependent electronic transport has been investigated on granular 99.95% La0.7Sr0.3MnO3-0.05% Paraffin wax nanocomposite. Although, the composite exhibits usual signature of spin-polarized tunnelling magnetoresistance (MR) of polycrystalline La0.7Sr0.3MnO3 (LSMO) within the temperature range of...

Zusammenfassung:Spin-dependent electronic transport has been investigated on granular 99.95% La0.7Sr0.3MnO3-0.05% Paraffin wax nanocomposite. Although, the composite exhibits usual signature of spin-polarized tunnelling magnetoresistance (MR) of polycrystalline La0.7Sr0.3MnO3 (LSMO) within the temperature range of 50–300 K; it differs significantly at low temperature region (T
