dc.description.abstract | We report on a two-dimensional magnetic nanocomposite material consisting of a monolayer of similar to 11 nm diameter colloidal gamma-Fe2O3 nanoparticles arrayed by the Langmuir-Blodgett method over a similar to 3 nm thin film of FePt deposited on a glass slide substrate, thus exploiting the advantages of both thin film fabrication and chemical synthesis. The FePt film was obtained by magnetron sputtering of a FePt target, followed by vacuum annealing at 600 degrees C. FePt magnetic polarization perpendicular to the film plane was observed. The parallel to the plane hysteresis loops are dominated by the diamagnetic glass substrate. The perpendicular to the plane hysteresis loops are highly square with a coercivity of 4.87x10(6)/4 pi (A/m), which upon deposition of the monolayer array of gamma-Fe2O3 nanoparticles increases to 6.31x10(6)/4 pi (A/m).
