Rare-earth-containing planar magnetic materials formed using Langmuir–Blodgett technique

Lanthanide-Containing Liquid Crystals and Surfactants

“…Xu et al prepared by a conventional Langmuir−Blodgett method multilayers and Y-type bilayers of pure and mixed erbium(III) hexadecanoate, erbium(III) nonadecanoate, and erbium(III) behenate on calcium fluoride substrates . Gadolinium(III)-containing Langmuir−Blodgett films were prepared with the aim to prepare planar magnetic materials. , Even less information than on LB films of lanthanide(III) alkanoates is available on LB films of lanthanide(III) complexes of aromatic carboxylic acids. Li and co-workers described the synthesis, spectroscopic properties, and LB-film formation of lanthanide complexes of monooctadecyl phthalate (MOP) .…”

Conducting and Magnetic Langmuir−Blodgett Films

“…LB films of gadolinium stearate − have been reported to show evidence of a magnetically ordered state with a transition temperature near 500 K. Changes in the EPR line width and resonance field are cited as evidence of ordering. , It is unlikely, though, that the as-deposited film retains its structure upon excursions to these temperatures. Surface inhomogeneites, seen even at room temperature, might be responsible for some of the reported observations.…”

Interfacially formed organized planar inorganic, polymeric and composite nanostructures

“…The LB technique allowed to prepare highly organized surfactant monolayers with molecular structure visualized by scanning probe microscopy techniques [71]. LB films containing planar arrays of transition metal cations were used as a model system for investigation of 2-D magnetism [72] and evidences for ferromagnetic ordering were obtained for gadolinium stearate LB films [73][74][75][76][77]. Metal soap LB films were used as layered metal-organic precursors for generation of ultrathin inorganic layers via thermal or plasma treatment [78].…”
