  • Grain boundaries in granular materials-A fundamental limit for thermal stability 

    Saharan, L; Morrison, C; Ikeda, Y; Takano, K; Miles, JJ; Thomson, T; Schrefl, T; Hrkac, G (American Institute of Physics (AIP), 2013)
    We show that thermal-stability and the associated switching field in well segregated, nanoscale granular materials is explained by grain boundary and interface effects. Grain boundaries pose a fundamental limit on scaling ...
