Multiferroic double perovskites: Opportunities, Issues and Challenges
M. P. Singh, K. D. Truong, S. Jandl +1
Despite the great technological and scientific importance, a well-controlled coupled behavior in magnetoelectric multiferroic materials at room temperature remains challenging. We…
Influence of Ni/Mn cation order on the spin-phonon coupling in multifunctional La2NiMnO6 epitaxial films by polarized Raman spectroscopy
K. D. Truong, M. P. Singh, S. Jandl +1
We report the influence of Ni/Mn ordering on the spin-phonon coupling in multifunctional La2NiMnO6. Three types of films with different levels of structural order, including long-r…
Long-range Ni/Mn structural order in epitaxial double perovskite La2NiMnO6 thin films
M. P. Singh, K. D. Truong, S. Jandl +1
We report and compare the structural, magnetic, and optical properties of ordered La2NiMnO6 thin films and its disordered LaNi0.5Mn0.5O3 counterpart. An x-ray diffraction study rev…
A radical approach to promote multiferroic coupling in double perovskites
M. P. Singh, K. D. Truong, P. Fournier +4
Double perovskites provide a unique opportunity to induce and control multiferroic behaviors in oxide systems. The appealing possibility to design materials with a strong coupling…
Stabilization and functional properties of La3NiAlMnO9 and La3CoAlMnO9 magnetoelectric triple perovskites
M. P. Singh, K. D. Truong, S. Jandl +1
Ferromagnetic La3NiAlMnO9 (LNAMO) and La3CoAlMnO9 (LCAMO) triple-perovskite thin films are stabilized in the 750-860 oC temperature range in 100 to 900 mTorr O2 pressure range usin…
Epitaxial thin films of the multiferroic double perovskite Bi2FeCrO6 grown on (100)-oriented SrTiO3 substrates: Growth, characterization, and optimization
Riad Nechache, Catalin Harnagea, Louis-Philippe Carignan +7
The influence of the deposition pressure PO2 and substrate temperature TS during the growth of Bi2FeCrO6 thin films grown by pulsed laser deposition has been investigated. It is fo…
