Influence of alkylphosphonic acid grafting on the electronic and magnetic properties of La2/3Sr1/3MnO3 surfaces

Fabrication of ultra-smooth and oxide-free molecule-ferromagnetic metal interfaces for applications in molecular electronics under ordinary laboratory conditions

“…Therefore, SAMs are immobilized on FM surfaces via this native oxide layer using carboxylate, phosphonate, or silane, anchoring groups. [26][27][28][29] The presence of a native oxide layer, however, oen forms an antiferromagnetic (AFM) passivation layer which hinders the reorientation of ferromagnetic moment of the FM layer by exchange coupling lowering the performance of, for example, spin valves. [30][31][32] Thus, to develop fabrication methods to obtain oxide free molecular-FM interfaces are important for molecular spintronics.…”

Surface‐Driven Magnetotransport in Perovskite Nanocrystals

“…The properties of these open surface electrodes exposed to atmosphere and solvents are however hard to reconcile with those of epitaxial (buried) interfaces in thin films grown under stringent high vacuum or controlled oxygen pressure conditions. Especially, quantitative measurements from surface studies [6,7] require measurements over large areas due to the limited sensitivity of experimental tools, so that nanoscale variations of electrical transport properties are not reported, [8] thus leaving an open question: how does spin transport occur at the surfaces and interfaces of LSMO nanostructures and how does it impact hybrid spintronics?…”

Hybrid Interfaces in Molecular Spintronics

“…The problem was solved in 2012 by using air stable ferromagnetic electrodes like LSMO. Thus, the use of alkylphosphonic acids in ethanolic solution gave rise to highly organized and compact SAMs, with a modified work function for LSMO that could permit the tailoring of the electron and spin injection efficiencies . This crucial step allowed Galbiati et al .…”
