Stochastic resonance in a bistable magnetic system
IEEE Transactions on Magnetics, 1995Theoretical model of magnetostochastic resonance is developed. It is shown that in the presence of noise the signal-to-noise ratio for a bistable uniaxial ferromagnetic can be a million times greater than that for a one-stable ferromagnetic. The phenomenon can be used for magnetic field measurements, detection of macroscopic quantum tunneling of ...

Crystal optical bistability in a magnetic field
SPIE Proceedings, 1999The influence of an external magnetic field on optical features of semiconductor exciton spectra is researched in this work. It is shown that the magnetic field brings about the shift of the exciton level in the high-energy spectrum area. This causes the arising of a unique effect-- brightening-- of the crystal on the fixed external excitement ...

Size-dependent bistability of magnetic states in soft magnetic cap arrays
NanotechnologyAbstract We have investigated the size dependent energy barrier regarding the transition between magnetic vortex and collinear states in dense arrays of magnetic cap structures hosting magnetic vortices. The cap structures were formed by the deposition of soft magnetic thin films on top of large arrays of densely packed polystyrene ...

The bistable behaviour of the magnetic transductor
British Journal of Applied Physics, 1958It is already well known that the second harmonic magnetic transductor has instability regions. It has been found experimentally that in each region two modes of output current exist, differing only by the phase, which these currents have with respect to the exciting voltage.

An Improved Magnetically Bistable Piezoelectric Energy Harvester
ASEE 2021 Gulf-Southwest Annual Conference ProceedingsBy modeling a piezoelectric cantilever beam system in which mechanical bistability emerges from repulsion between a stationary magnet and magnetic tip mass, the size of the basin of attraction for interwell oscillations is increased, so that the higher-energy solutions to the system may be more readily acquired than in previously studied systems.
