Preparation of a vast CoFe2O4 magnetic monolayer by Langmuir-Blodgett technique

Pressure-area isotherm curves and Brewster Angle Microscope (BAM) were used for examining the formation and stability of a Langmuir monolayer of the surface coated CoFe2O4 nanocrystallites with oleate at the air/water interface. The well-separated domains of nanocrystallites transformed into well-compressed, monoparticulate layers, due to the increase in surface pressure.
