“…A possible advantage of utilizing the frustrated system is that the competing magnetic interactions can be easily perturbed by the chemical-doping procedure on the specific magnetic site, which may enable the sensitive control of competing multiferroic phases and/or the ME property, as exemplified by the case of Ga-and Al-doping-induced stabilization of the ferroelectric phase in the triangularlattice antiferromagnet CuFeO 2 [13], for instance, and Zn-doping-induced modulation of the multiferroic phase in MnWO 4 [14]. One of the problems of this strategy is that the ion-substitution may easily dilute the magnetism and also the magnitude of the ME signal.…”

Spin-wave and electromagnon dispersions in multiferroicMnWO4as observed by neutron spectroscopy: Isotropic Heisenberg exchange versus anisotropic Dzyaloshinskii-Moriya interaction

“…As a prototypical multiferroic material with spiral magnetic order, MnWO 4 has been widely studied concerning its magnetic and ferroelectric properties [28][29][30][31][32][33][34][35][36][37][38] . It is well accepted that the inverse DM mechanism is relevant for modeling the ME coupling in MnWO 4 .…”

“…In order to enlarge the temperature range where the multiferroic phase is stable, MnWO 4 has been doped with isovalent metal and nonmetal ions. [13][14][15][16][17][18][19][20] It turned out that doping with Co 2+ is particularly interesting since it strongly stabilizes the multiferroic phase at low temperatures. According to preliminary data on powder samples, 16 the incommensurate multiferroic AF2 phase is expected to substitute the commensurate AF1 ordering at low temperature for cobalt doping above 3%.…”
