Journal ArticleDOI
Electric- and magnetic-field-driven nonlinear charge transport and magnetic ordering in epitaxial films of Pr 0.7 Ca 0.3-x Sr x MnO 3
TL;DR: In this article, electric and magnetic-field-dependent resistivity and magnetization are studied in epitaxial films of the canonical charge-ordered (CO) insulator, and it is shown that the nonlinear and hysteretic effects seen in samples with $xl~0.1$ are a result of classical percolation and quantum transport in a topologically inhomogeneous medium.
Journal ArticleDOI
Interfacial disorder-driven metal-insulator transition and enhanced low-temperature magnetoresistance in La 0.7 Ca 0.3 MnO 3 / LaNiO 3 superlattices
Prahallad Padhan,R. C. Budhani +1 more
TL;DR: In this paper, the temperature and magnetic-field-dependent resistivity of La 0. 7 Ca 0. 3 MnO 3 /LaNiO 3 superlattices grown on (001)-oriented SrTiO 3 and LaAlO 3 substrates is compared as a function of LaNiO3 spacer layer thickness.
Journal ArticleDOI
Overdamped interlayer exchange coupling and disorder-dominated magnetoresistance in La0.7Ca0.3MnO3/LaNiO3 superlattices
TL;DR: Magnetization and magnetoresistance measurements on superlattices consisting of alternate layers of 20 unit cell (u.c.) thick La0.7Ca0.3MnO3 (LCMO) and n u.c. LaNiO3, where n varies from 1 to 10, are reported in this paper.
Journal ArticleDOI
Transition from a double exchange ferromagnetic metal to hysteretic insulator mimicking charge ordering effects in ultra-thin epitaxial films of a perovskite manganite
TL;DR: Magnetic and electric field dependent charge transport in epitaxial films of La 0.7 Ca 0.3 MnO 3 deposited on (001) SrTiO 3 and LaAlO 3 substrates is compared as a function of the film thickness as mentioned in this paper.
Journal ArticleDOI
Giant quenching and mobile-carrier-assisted recovery of ordered moments in La 0.7 Ca 0.3 Mn O 3 ∕ Er 0.7 Sr 0.3 Mn O 3 and La 0.7 Ca 0.3 Mn O 3 ∕ La Ni O 3 superlattices

TL;DR: In this paper, the magnetic ordering temperature, magnetic moment, and resistivity of thin film superlattices were measured and attributed to random pinning of the spins of Mn ions in a disordered interfacial zone of length scale.
