Crystallographic texture determinations from inverse susceptibility measurements

TL;DR: In this article, the analysis of inverse paramagnetic susceptibility measurements constitutes a new method to investigate crystallographic texture and magnetic properties in advanced permanent magnets, and is used to evaluate magnetic measurements taken from a series of Nd{sub 2}Fe{sub 14}B magnets that have been processed by different means and thus contain different degrees of texture.
Journal ArticleDOI

En route to next-generation nerve repair: static passive magnetostimulation modulates neurite outgrowth

TL;DR: In this paper , the effects of DC magnetostimulation on primary neuronal outgrowth in vitro were quantified, showing that the combined action of in-plane + out-of-plane (IP + OOP) magnetic field application produced a directional outgrowth bias parallel to the IP field direction.

Discovery and implications of hidden atomic-scale structure in a metallic meteorite

TL;DR: In this paper, the existence of a previously hidden FeNi nanophase within the extremely slowly cooled metallic meteorite NWA 6259 has been revealed, along with Ni-poor and Ni-rich nanoprecipitates within a matrix of tetrataenite, the uniaxial, chemically ordered form of FeNi.
Journal ArticleDOI

Toward remote and secure authentication: Disambiguation of magnetic microwire signatures using neural networks

TL;DR: In this paper , complex electromagnetic responses from arrangements of amorphous ferromagnetic microwires were analyzed using machine learning, and a neural network reproduced the response distribution of unseen data to a confidence level of 90%, with a mean square error less than 0.01.
Journal ArticleDOI

Aberration corrected STEM of iron rhodium nanoislands

TL;DR: In this article, the authors used scanning transmission electron microscopy (STEM) electron energy loss spec-troscopy (EELS) and high angle annular dark field (HAADF) techniques to analyze the FeRh nanoislands of equiatomic composition.
