“…In fact, FMR has been experimentally shown [15,16] to be sensitive to acoustic waves in ferromagnetic-ferroelectric structure. To our knowledge, multiferroic FMR, as suggested below has not yet been realized experimentally for the chosen interface, though several studies are known for multiferroic interfaces with other types of ME-coupling [17,18]. To be specific, we focus on a special class of ME coupled materials, so-called composite MFs [6,19], that may be synthesized from a wide range of materials that, when composed together yield a strong ME coupling and stable ferroelectric (FE) and ferromagnetic (FM) orders at room temperatures.…”
