Sinter-free phase conversion and scanning transmission electron microscopy of FePt nanoparticle monolayers
NANOSCALE, 3(10), 4142–4149.
Contributors: n, G. Scarel n, J. Wang n, G. Parsons n & J. Tracy n
MeSH headings : Aluminum Oxide / chemistry; Iron / chemistry; Magnetics; Metal Nanoparticles / chemistry; Metal Nanoparticles / ultrastructure; Microscopy, Electron, Scanning Transmission; Particle Size; Platinum / chemistry; Temperature
TL;DR:
Electron and X-ray diffraction in conjunction with high-angle annular dark-field scanning transmission electron microscopy (HAADF-STEM) show that as-synthesized A1 FePt NPs convert into L1(0) and L1 (2) phase NPs through annealing, highlighting the need for improved control over the compositional uniformity of FePT NPs for their use in bit-patterned magnetic recording.
