Abstract

The magnetic and transport properties of the Ga-doped charge-ordering state La 0.5 Ca 0.5 MnO 3 have been studied, A current-dependent large positive magnetoresistance (1080%) at 5 K was observed. These observations are interpreted in terms of the spin-dependent tunnelling process between ferromagnetic clusters embedded in an antiferromagnetic matrix.
