2011 journal article

Sinter-free phase conversion and scanning transmission electron microscopy of FePt nanoparticle monolayers

NANOSCALE, 3(10), 4142–4149.

By: A. Johnston-Peck n, G. Scarel n, J. Wang n, G. Parsons n  & J. Tracy n 

Contributors: A. Johnston-Peck 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.

Phonon Response in the Infrared Region to Thickness of Oxide Films Formed by Atomic Layer Deposition

APPLIED SPECTROSCOPY, 64(1), 120–126.

By: G. Scarel n, J. Na n, B. Gong n & G. Parsons n 

author keywords: Berreman effect; Optical phonons; Infrared spectroscopy; Transmission; Thin oxide films; Atomic layer deposition
TL;DR: The Berreman thickness is shown to be the upper limit for a linear relationship between oxide film thickness and phonon absorbance in the infrared region in transmission configuration, and it is estimated that it is around approximately 435 nm for zinc oxide films. (via Semantic Scholar)
