Title: Ferronics vs. Magnonics

Speaker: Prof. Gerrit E.W. Bauer (包格瑞), KITS, WPI-AIMR, ZIAM

Time: June 23 (Thursday), 10:00

Place: Rm M830, IOP-CAS



Ferromagnets and ferroelectrics are phases of condensed matter in which magnetic and electric dipoles align spontaneously below a Curie temperature. “Magnons” (“ferrons”) are the elementary excitations of the magnetic (electric) order that carry spin (electric) polarization, momentum and energy. I will present a short overview and selected theoretical results in magnonics and ferronics and compare with available experiments.
