Aging and Memory Effects in Superparamagnets and Superspin Glasses
M. Sasaki, P. E. Jönsson, H. Takayama +1
Many dense magnetic nanoparticle systems exhibit slow dynamics which is qualitatively indistinguishable from that observed in atomic spin glasses and its origin is attributed to di…

Absence of rejuvenation in a Superspin Glass
P. E. Jönsson, H. Yoshino, H. Mamiya +1
Effects of temperature changes on the nonequilibrium spin-glass dynamics of a strongly interacting ferromagnetic nanoparticle system (superspin glass) are studied. In contrary to a…
