Probing local magnetic cluster development in (CuZr)93−xAl7Gdx bulk metallic glasses by 27Al NMR
Source abstract
Abstract
We report magnetization properties of (CuZr)(93-x)Al7Gdx bulk metallic glasses from temperature dependent Al-27 nuclear magnetic resonance spectroscopy and magnetic susceptibility measurements. Significant non-linear line broadening of Al-27 spectra commencing at high temperatures is attributed to the development of a local magnetic susceptibility distribution that prevails over a finite temperature range. Magnetization measurements confirm the linewidth enhancement due to strong frustrated magnetic short-range order. This study provides insight into the nature of magnetic development and frustration in paramagnetic systems. (c) 2011 Elsevier B.V. All rights reserved.
