Textured Manganite Films Anywhere [PDF]

ACS Applied Materials & Interfaces, 2019
New paradigms are required in microelectronics when the transistor is in its downscaling limit and integration of materials presenting functional properties not available in classical silicon is one of the promising alternatives. Here, we demonstrate the possibility to grow La0.67Sr0.33MnO3 (LSMO) functional materials on amorphous substrates with ...

Omnipolar Magnetic Field Detection by Superlattice‐Based Hall Sensor

Advanced Functional Materials, EarlyView.
Magnetic‐field‐induced electronic switching is demonstrated in unit‐cell‐engineered La0.7Sr0.3MnO3–BiFeO3 superlattices. Distinct substrate terminations modify magnetic and transport properties. Hall resistance measurements show omnipolar, hysteretic anomalous Hall switching above the Curie temperature, arising from Fe─Mn interfacial exchange, enabling

Tuning Magnetoconductivity in LaMnO₃ NPs through Cationic Vacancy Control

Nanomaterials, 2023
The inclusion of La-Mn vacancies in LaMnO3 nanoparticles leads to a noticeable change in conductivity behavior. The sample retains its overall insulator characteristic, with a typical thermal activation mechanism at high temperatures, but it presents ...

Metastable Resistivity States and Conductivity Fluctuations in Low-doped La$_{1-x}$Ca$_{x}$MnO$_3$ Manganite Single Crystals

, 2012
Conductivity noise in dc current biased La_{0.82}Ca_{0.18}MnO_{3} single crystals has been investigated in different metastable resistivity states enforced by applying voltage pulses to the sample at low temperatures.

Electric Field Induced Collapse of Charge-Ordered Phase in Manganites [PDF]

, 2006
The colossal electroresistance in manganites is a concomitant of the electric field induced insulator-to-metal phase transition. A phenomenological phase transition model is proposed to study this electric field induced collapse of charge-ordered phase ...

Oxygen Vacancies Driven Photoconductivity in Layered Cobaltite Epitaxial Films

Advanced Electronic Materials, EarlyView.
ABSTRACT Understanding photoinduced phenomena in complex oxides is crucial for developing next‐generation optoelectronic devices. Here, we report pronounced ultraviolet (UV) light‐induced photoconductivity in epitaxial PrBa1‐xCaxCo2O5+δ (x = 0.5) thin films grown on (001) LSAT substrates via pulsed laser deposition.
