A Perspective on Ferrons
read the original abstract
The duality between electric and magnetic dipoles in electromagnetism only partly applies to condensed matter. In particular, the elementary excitations of the magnetic and ferroelectric orders, namely magnons and ferrons, respectively, have received asymmetric attention from the condensed matter community in the past. In this perspective, we introduce and summarize the current state of the budding field of "ferronics" and speculate about its potential applications in thermal, information, and communication technology.

Ferron Hall effect: Transverse accumulation of polarization driven by thermal gradients in ferroelectrics
Ferron Hall effect generates transverse polarization accumulation in ferroelectrics via thermal gradients acting on polarized phonons called ferrons.

Lattice excitations with finite polarization and magnetization
Multiferrons are defined as elementary excitations with both electric and magnetic character that tilt polarization, generate magnetization via dynamical multiferroicity, and carry quadrupole and octupole moments, as ...
