Tunable Finite-Sized Chains to Control Magnetic Relaxation
Paul D. Ekstrand, Daniel J. Javier, Thomas Gredig
The magnetic dynamics of low-dimensional iron ion chains have been studied with regards to the tunable finite-sized chain length using iron phthalocyanine thin films. The depositio…
Angular Dependence of Vortex Annihilation Fields in Asymmetric Co Dots
Randy K. Dumas, Thomas Gredig, Chang-Peng Li +2
Shape asymmetries in nominally circular nanomagnets provide a potential means for vortex chirality control. However, in realistic arrays their effects are challenging to probe sinc…
Asymmetric Magnetization Reversal in a Single Exchange-Biased Micro Bar
T. Gredig, M. Tondra
The asymmetric magnetization reversal is studied in a single exchange-biased microbar of 1.5 x 13 micrometer with anisotropic magnetoresistance and magnetic force microscopy. The p…
Ferromagnetic Domain Distribution in Thin Films During Magnetization Reversal
W. -T. Lee, S. G. E. te Velthuis, G. P. Felcher +3
We have shown that polarized neutron reflectometry can determine in a model-free way not only the mean magnetization of a ferromagnetic thin film at any point of a hysteresis cycle…
