| Comparison between simulation and experiment for nanoparticles either in
either a frozen or melted state. Spectroscopy was performed with a
26-kHz, 31 mT/μ0
field. The log-normal distributions of particle diameter and anisotropy
constant are shown on the right by number in a representative
1000-particle subsample. |
