Bias sputtering of granular -FePt films with hexagonal boron nitride grain boundaries
Chengchao Xu, B. S. D. Ch. S Varaprasad, David E. Laughlin +2
In this paper, we present an experimental study of -FePt granular films with crystalline/amorphous boron nitride (BN) grain boundary materials for heat assisted magnet…
Understanding the growth of high-aspect-ratio grains in granular L10-FePt thin-film magnetic media
Chengchao Xu, Bing Zhou, Tianxiang Du +4
A systematic investigation has been performed to optimize the microstructure of granular thin film as recording media for heat-assisted magnetic recordin…
On the Formation of Solid States Beyond Perfect Crystals: Quasicrystals, Geometrically-Frustrated Crystals and Glasses
Caroline S. Gorham, David E. Laughlin
There are three kinds of solid states of matter that can exist in physical space: quasicrystalline (quasiperiodic), crystalline (periodic) and amorphous (aperiodic). Herein, we con…
Solidification of Icosahedral Quasicrystals: Viewpoint Based on a Quaternion Orientational Order Parameter and the Formation of the E8 Lattice
Caroline S. Gorham, David E. Laughlin
In this article, the solidification phase transition between isotropic liquids and icosahedral quasicrystalline structures is classified by the application of a quaternion orientat…
Crystallization in Three-Dimensions: Defect-Driven Topological Ordering and the Role of Geometrical Frustration
Carline S. Gorham, David E. Laughlin
Herein, fundamentals of topology and symmetry breaking are used to understand crystallization and geometrical frustration in topologically close-packed structures. This frames soli…
The effect of adding magnetic oxide as grain boundary for HAMR
Bing Zhou, B. S. D. Ch. S. Varaprasad, Zhengkun Dai +2
Grain-to-grain Curie temperature (Tc) variation in the media reduces signal-to-noise ratio due to its contribution in transition jitter noise, especially when average grain size is…
