چکیده
The electromotive force induced by a moving magnetic domain wall in a nanostrip has been calculated theoretically and detected experimentally. It is found that the emf depends only on the domain wall transformation frequency through a universal Josephson type relation, which is closely related to the topological nature of the domain wall. Our experimental measurements confirm the theoretical prediction.

Currents induced by domain wall motion in thin ferromagnetic wires
Historically the role of eddy currents in the motion of Bloch walls has been extensively studied. In contrast the direct interaction of currents with such a moving wall has received very little attention. However recently it has been shown that a wall can be displaced by the effects of a current alone, a fact which is important to the development of spintronics. We report here that such a movin...
متن کاملLetter to the Editor Mean electromotive force and dynamo action in a turbulent flow
We derive the expression for the mean electromotive force in a turbulent flow taking into account stretching of turbulent magnetic field lines and streamlines by the mean flow. Shear stresses break the symmetry of turbulence in such a way that turbulent motions become suitable for the dynamo action. The contribution of this effect to themean electromotive force is proportional to the production...
متن کاملEnergy landscape scheme for an intuitive understanding of complex domain dynamics in ferroelectric thin films
Fundamental understanding of domain dynamics in ferroic materials has been a longstanding issue because of its relevance to many systems and to the design of nanoscale domain-wall devices. Despite many theoretical and experimental studies, a full understanding of domain dynamics still remains incomplete, partly due to complex interactions between domain-walls and disorder. We report domain-shap...
متن کاملCan the History Force be Neglected for the Motion of Particles at High Subcritical Reynolds Number Range?
In the present work, the motion of metallic and plastic particles of 5 mm diameter falling in a quiescent fluid is investigated experimentally. The goal of this investigation is to examine the effect of history force acting on a particle in a range of Reynolds numbers between 1000 and 5000. The instantaneous position of the particle was recorded using a high - speed camera (500 to 1000 frames p...
