Spin flexoelectricity and chiral spin structures in magnetic films

, 2015
In this short review a broad range of chiral phenomena observed in magnetic films (spin cycloid and skyrmion structures formation as well as chirality dependent domain wall motion) is considered under the perspective of spin flexoelectricity, i.e the ...

Flexoelectricity driven elastic contact–separation model for triboelectrification

Friction
Triboelectrification is the transfer of electrical charge between surfaces during contact. When the contact is purely normal (i.e., no sliding), the term contact electrification is often used.
