Magnetoresistive memory in phase separated La${}_{0.5}$Ca${}_{0.5}$MnO${}_3$

Abstract

We have studied a non volatile memory effect in the mixed valent compound La${}_{0.5}$Ca${}_{0.5}$MnO${}_3$ induced by magnetic field (H). In a previous work [R.S. Freitas et al., Phys. Rev. B 65 (2002) 104403], it has been shown that the response of this system upon application of H strongly depends on the temperature range, related to three well differentiated regimes of phase separation occurring below 220 K. In this work we compare memory capabilities of the compound, determined following two different experimental procedures for applying H, namely zero field cooling and field cooling the sample. These results are analyzed and discussed within the scenario of phase separation.
