Effects of cation disorder on terahertz emission from half-doped manganite thin films

, 2007
We have observed terahertz (THz) emission from antiferromagnetic charge-ordered “undoped” Nd0.5Ca0.5MnO3 and “Ba-doped” Nd0.5Ca0.48Ba0.02MnO3 manganites by illuminating femtosecond laser pulses on the optical switch fabricated on highly oriented thin ...

Polarity Switchable Photovoltages in Miscut La0.67Ca0.33MnO3 Films

International Journal of Photoenergy, 2012
We report the transient laser-induced anomalous photovoltaic effect in the La0.67Ca0.33MnO3 film grown on miscut LaSrAlO4 (001) substrate under 248 nm pulsed laser irradiation at ambient temperature without any applied bias.

Controllable magnetization and resistivity jumps of manganite thin films on BaTiO3 substrate

AIP Advances, 2015
Manganites thin films grown on ferroelectric BaTiO3 (BTO) exhibit dramatic jumps for both magnetization and resistivity upon cooling in accordance with the temperature-dependent structural transitions of the BTO substrate.

Physical and structural studies of chemical Vapor deposited lacunar neodymium manganite thin films

EPJ Web of Conferences, 2012
Lacunar Nd1-xMnO3-δ thin films were successfully deposited by a liquid source metal-organic MOCVD technique on (001) SrTiO3 (STO), LaAlO3 (LAO) and Si substrates. Optimal growth conditions are reported.

Uniaxial magnetic anisotropy induced low field anomalous anisotropic magnetoresistance in manganite thin films

APL Materials, 2014
La2/3Sr1/3MnO3 films with uniaxial magnetic anisotropy were coherently grown on NdGaO3 (110) substrates. The uniaxial anisotropy has strong effect on magnetoresistance (MR).

Fast Two-stage Protector Against Electromagnetic Pulse Based on Electroresistance Effect in Polycrystalline La-Sr(Ca)-Mn-O Films

Medžiagotyra, 2014
The electroresistance (ER) effect in polycrystalline films of La0.83Sr0.17MnO3 and La0.7Ca0.3MnO3 was investigated in the temperature range of (5 – 290) K using high power sub-nanosecond rise time electrical pulses with amplitude up to 1 kV.

A-site ordering and stripe phases in manganite films

Physica B: Condensed Matter, 2008
Abstract Insulating and metallic stripes above and below the Curie temperature, TC, respectively, were observed by a high-resolution scanning tunneling microscopy (STM) and/or spectroscopy (STS) in A-site ordered and macroscopically strain free epitaxial La0.75Ca0.25MnO3 film grown on MgO substrate.

Resistive switching at manganite/manganite interfaces

, 2011
: We report bipolar resistive switching between the interfaces of manganite nanocolumns. La0.7Sr0.3MnO3 films were prepared on Al2O3 substrates, where the films grow in nanocolumns from the substrate to the surface.
