Laura H. Lewis,Konrad Bussmann +1 more
TL;DR: In this article, the authors present a unique design of a sample holder and accompanying calibration technique used to obtain accurate magnetic moment values from compact, low-susceptibility samples measured with the quantum design magnetic properties measurement system superconducting quantum interference device (SQUID) magnetometer.
Journal ArticleDOI
Quantification of the strain-induced promotion of τ-MnAl via cryogenic milling
TL;DR: In this article, the evolution of phase composition, microstructure, chemical order and magnetic attributes accompanying the direct transformation of ϵ-MnAl to τ-mnAl has been quantified as a function of time spent processing via mechanical milling at cryogenic temperatures.
