Dynamic transitions and hysteresis [PDF]
When an interacting many-body system, such as a magnet, is driven in time by an external perturbation, such as a magnetic field,the system cannot respond instantaneously due to relaxational delay.

Dynamic hysteresis in Finemet thin films [PDF]
We performed a series of dynamic hysteresis measurements on three series of Finemet films with composition Fe$_{73.5}$Cu$_1$Nb$_3$Si$_13.5$B$_9$, using both the longitudinal magneto-optical Kerr effect (MOKE) and the inductive fluxometric method.

Dynamic hysteresis from zigzag domain walls [PDF]
We investigate dynamic hysteresis in ferromagnetic thin films with zigzag domain walls. We introduce a discrete model describing the motion of a wall in a disordered ferromagnet with in-plane magnetization, driven by an external magnetic field ...

Dynamical Hysteresis without Static Hysteresis: Scaling Laws and Asymptotic Expansions [PDF]
Summary: We study dynamical hysteresis in a simple class of nonlinear ordinary differential equations, namely first-order equations subject to sinusoidal forcing. The assumed nonlinearities are such that the area of the hysteresis loop vanishes as the forcing frequency tends to zero; in other words, there is no static hysteresis.

Dynamics of successive minor hysteresis loops [PDF]
Cumulative growth of successive minor hysteresis loops in Co/Pd multilayers with perpendicular anisotropy was studied in the context of time dependent magnetization reversal dynamics. We show that in disordered ferromagnets, where magnetization reversal involves nucleation, domains' expansion and annihilation, differences between the time dependencies ...

Surface mobility and structural transitions of poly(n-alkyl methacrylates) probed by dynamic contact angle measurements [PDF]
Dynamic contact angles and contact-angle hysteresis of a series of poly(n-alkyl methacrylates) (PAMA) were investigated using the Wilhelmy plate technique.

Relaxation in Population Dynamics Models with Hysteresis [PDF]
The present paper is concerned with a nonlinear partial differential control system subject to a state-dependent and nonconvex control constraint. This system models the dynamics of populations in the vegetation--prey--predator framework and takes account of diffusive and hysteresis effects appearing in the process.

Investigation of scaling properties of hysteresis in Finemet thin films [PDF]
We study the behavior of hysteresis loops in Finemet Fe$_{73.5}$Cu$_1$Nb$_3$Si$_{18.5}$B$_4$ thin films by using a fluxometric setup based on a couple of well compensated pickup coils.

Hidden hysteresis – population dynamics can obscure gene network dynamics [PDF]
Positive feedback is a common motif in gene regulatory networks. It can be used in synthetic networks as an amplifier to increase the level of gene expression, as well as a nonlinear module to create bistable gene networks that display hysteresis in response to a given stimulus. Using a synthetic positive feedback-based tetracycline sensor in E.

Comparator with dynamic hysteresis
A comparator is presented which is based on the use of a time domain phenomenon called 'dynamic hysteresis'. This comparator features only one threshold and a short-time controllable noise immunity.
