Overwrite in thin film disk recording systems
Overwrite in thin film rigid disk recording has been studied experimentally using disks with a wide range of magnetic moment and coercivity. Standard f2/f1 overwrite was investigated in detail at various recording currents ...
Disorder and coercivity in magnetic particle systems
Computer simulation has been utilized to understand the hysteretic behavior of magnetic particle systems. Particles are assumed to be single domain, spherical in shape, and possess no intrinsic anisotropy. Neighboring spins ...
Micromagnetic modeling of magnetic anisotropy in textured thin-film media
Existing micromagnetic models, based on single domain grains that individually follow coherent rotation during reversal, have been utilized to study the effect of various texture-induced microstructures on the hysteretic ...
Superradiance coherence sizes in single-molecule spectroscopy of LH2 antenna complexes
The distribution of cooperative radiative decay rates in photosynthetic aggregates is calculated using a Frenkel exciton model with static diagonal disorder. This distribution which depends on both the exciton coherence ...
