Colossal enhancement of magnetoresistance in La${}_{0.67}$Sr${}_{0.33}$MnO${}_3$ / Pr${}_{0.67}$Ca${}_{0.33}$MnO${}_3$ multilayers: reproducing the phase-separation scenario

Abstract

Colossal enhancement of magnetoresistance has been achieved over a broad temperature range which extends upto the room temperature, in ferromagnetic metal-charge ordered insulator manganite multi-layers. The artificially created phase coexistence in the multilayers reproduce the characteristic signatures of metastability in the magnetotransport properties commonly observed in electronically phase-separated manganites.
