Dynamic hysteresis from zigzag domain walls [PDF]
, 2006 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 ...

Dynamic hysteresis in Finemet thin films [PDF]
IEEE Transactions on Magnetics, 2003 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 transitions and hysteresis [PDF]
Reviews of Modern Physics, 1998 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.

Research on the Dynamic Hysteresis Loop Model of the Residence Times Difference (RTD)-Fluxgate [PDF]
Sensors, 2013 Based on the core hysteresis features, the RTD-fluxgate core, while working, is repeatedly saturated with excitation field. When the fluxgate simulates, the accurate characteristic model of the core may provide a precise simulation result.

A Loss Separation-Based Dynamic Jiles–Atherton–Bingham Model for Magnetorheological Dampers [PDF]
SensorsMagnetorheological (MR) dampers exhibit significant hysteretic nonlinearities, particularly under dynamic operating conditions, where accurately modeling the complex coupling between magnetic flux density and excitation current remains challenging.
