Magnon-phonon coupling in magnetoelectric HoMnO3

, , , , &
The manipulation of magnetic properties electronically is of great importance in modern computing. Current technology uses electric currents which draws a relatively large amount of power. An alternative scheme uses electric fields to control the magnetic properties via the magnetoelectric effect and this could reduce energy dissipation by as much as a factor of 100. One promising material is HoMnO3. Here, an applied electric field distorts the crystal structure, changing the magnetic interactions and consequently...
