Developing highly active and stable catalysts based on earth-abundant elements for oxygen electrocatalysis is critical to enable efficient energy storage and conversion. In this work, we took advantage of the high intrinsic oxygen reduction reaction (ORR) activity of La(0.8)Sr(0.2)MnO(3-δ) (LSMO) and the high intrinsic oxygen evolution reaction (OER) activity of Ba(0.5)Sr(0.5)Co(0.8)Fe(0.2)O(3-...

In this paper the optical and electrical characterization of a 75 × 75 μm2 uncooled bolometers based on free-standing La0.7Sr0.3MnO3 /CaTiO3 (LSMO/CTO) thin films fabricated by micromachining of the silicon substrates is presented. R(T) curves have been compared to electro thermal simulations. Its thermal conductance was measured to be 9 × 10−6 W·K−1 around 300 K. The optical characterization w...

We report the integration of high-quality epitaxial La2/3Sr1/3MnO3 (LSMO) thin films onto SrTiO3 buffered Silicon-on-Sapphire (SOS) substrates by combining state-of-the-art film growth techniques such as molecular beam epitaxy and pulsed laser deposition. Detailed structural, magnetic electrical characterizations LSMO/STO/SOS heterostructures show that LSMO properties are competitive with those...

The combination of spin-orbit coupling driven effects and multiferroic tunneling properties is explored experimentally in thin Pt/Co/BaTiO3(BTO)/La2/3Sr1/3MnO3(LSMO) multilayers. presence a Pt heavy metal allows for the spin current-induced magnetization precession Co upon radio-frequency charge current injection. utilization BTO ferroelectric tunnel barrier separating LSMO ferromagnetic electr...

We investigate the interfacial chemistry of secondary Fe₂O₃ phases formed in a BiFeO₃ (BFO) layer in BFO/ La0.67Sr0.33MnO₃ (LSMO)/SrTiO₃ (STO) heterostructures. A combination of high-resolution spherical aberration corrected scanning TEM and spectroscopy results, reveals that specific chemical and crystallographic similarities between Fe₂O₃ and BFO, enable the BFO layer to form a facile host fo...

Structural features and magnetic behaviour of TbPc2 thin films sublimated on LSMO and on cobalt surfaces have been investigated by synchrotron-based XNLD and XMCD techniques. Different orientation of the molecules is observed for the two substrates. No significant magnetic interaction with the ferromagnetic substrates is detected.

Spin–orbit torques (SOTs) that arise from materials with large spin–orbit coupling offer a new pathway for energy-efficient and fast magnetic information storage. SOTs in conventional heavy metals topological insulators are explored extensively, while 5d transition metal oxides, which also host ions strong coupling, relatively territory the field of spintronics. An all-oxide, SrTiO3 (STO)//La0....

Our studies of compressively strained La0.7Sr0.3MnO7 ~LSMO! thin films reveal the importance of domain structure and strain effects in the magnetization reversal and magnetotransport. Normal and grazing incidence x-ray diffraction indicate that the compressive strain on these LSMO thin films on ~100! LaAlO3 is not completely relaxed up to thicknesses on the order of 1000 Å. The effect of the co...

We report the creation of a multiferroic field effect device with a BiFeO(3) (BFO) (antiferromagnetic-ferroelectric) gate dielectric and a La(0.7)Sr(0.3)MnO(3) (LSMO) (ferromagnetic) conducting channel that exhibits direct, bipolar electrical control of exchange bias. We show that exchange bias is reversibly switched between two stable states with opposite exchange bias polarities upon ferroele...
