  • 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 ...
  • Modelling interfacial coupling in thin film magnetic exchange springs at finite temperature 

    Saharan, L; Morrison, C; Miles, JJ; Thomson, T; Schrefl, T; Hrkac, G (American Institute of Physics (AIP), 2013)
    We report a numerical study that demonstrates the interface layer between a soft and hard magnetic phase, the exchange transition layer, is the dominant factor that influences the magnetization reversal process at room ...
