Fabrication of magnetic FePt patterns from Langmuir-Blodgett films of platinum-iron oxide core-shell nanoparticles
The patterned Langmuir-Blodgett (pLB) technique has been used to generate micrometer-sized structures of Pt@Fe2O3 core-shell nanoparticles. The composition of these core-shell nanoparticles has been further converted in situ into face-centered tetragonal phase FePt, one of the best candidates for ultra-high-density magnetic-storage media without loss of the pattern (see Figure).
