Fragility of the spin-glass-like collective state to a magnetic field in an interacting Fe-C nanoparticle system
P. E. Jönsson, S. Felton, P. Svedlindh +2
The effect of applied magnetic fields on the collective nonequilibrium dynamics of a strongly interacting Fe-C nanoparticle system has been investigated. It is experimentally shown…
Critical dynamics of an interacting magnetic nanoparticle system
M. F. Hansen, P. Jönsson, P. Nordblad +1
Effects of dipole-dipole interactions on the magnetic relaxation have been investigated for three Fe-C nanoparticle samples with volume concentrations of 0.06, 5 and 17 vol%. While…
Spin glass like transition in a highly concentrated Fe-C nanoparticle system
P. Jönsson, P. Svedlindh, P. Nordblad +1
A highly concentrated (17 vol.%) Fe-C nano-particle system, with a narrow size distribution nm, has been investigated using magnetic ac susceptibility measurements…
Non-equilibrium dynamics in an interacting nanoparticle system
P. Jönsson, M. F. Hansen, P. Nordblad
Non-equilibrium dynamics in an interacting Fe-C nanoparticle sample, exhibiting a low temperature spin glass like phase, has been studied by low frequency ac-susceptibility and mag…
