Orientational Ordering in Solid N2-Argon Mixtures: Collective Versus Non-Collective Behavior

Abstract
We compare the temperature variation of the local orientaional order parameters and the Edwards-Anderson glass order parameter decduced from available NMR data, With the variations expected for a non-Collective local random quadrupolar field model. The analysis of the experimental results for solid N2-Argon allowy indicates a weak collective behavior and new experiments are suggested to test for true glassy behavior.
