Magnons are the elementary excitations of the magnetic order that carry spin, momentum, and energy. Here we compare the magnon with the ferron, i.e. the elementary excitation of the electric dipolar order, that transports polarization, momentum, and energy in ferroelectrics.

Magnonics 与 Ferronics

磁子是携带自旋、动量和能量的磁序的基本激发。在这里，我们比较磁振子与Ferron的，即电偶极秩序的基本激励，即运输极化，动量和能量在铁电体。
