Fingerprinting hysteresis

We test the predictive power of first-order reversal curve (FORC) diagrams using simulations of random magnets. In particular, we compute a histogram of the switching fields of the underlying microscopic switching units along the major hysteresis loop, and compare to the corresponding FORC diagram. We find qualitative agreement between the switching-field histogram and the FORC diagram, yet dif...

Critical Hysteresis

Hysteresis is observed at second order phase transitions. Universal scaling for-mulae for the areas of hysteresis loops are written down. Critical exponents are defined, and related to other exponents for static and dynamic critical phenomena. These relations are verified with Langevin dynamics in both the critical and tricriti-cal mean-field models. A finite-size scaling relation is tested in ...

Torque Calculation of Hysteresis Motor Using Vector Hysteresis Model

This paper presents how to determine the thickness of hysteresis ring of hysteresis motor using the finite element method combined with a vector hysteresis model. From the magnitude and direction of the magnetic field intensity, the magnetization of each ring element is calculated by the vector hysteresis model and the torque can be obtained from the vector sum of each torque of each element or...

Dynamical Hysteresis without Static Hysteresis: Scaling Laws and Asymptotic Expansions

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. Using regular and singular perturbation techniques, we derive the first te...

Hysteresis in RAIM

Absolute RAIM algorithms proposed for vertical guidance are based on a snapshot approach. At a given time, each satellite has a probability of being in a faulted state which does not depend on how long the satellite has been in view. This approach greatly simplifies the proof of safety. Both the threat model and the algorithm are simple enough so that the Probability of Hazardously Misleading I...
