MAGNETOELASTICITY AND MAGNETOPIEZOELECTRIC EFFECT IN HoFe3(BO3)4 Kolodiazhna M.P.1, Bilych I.V.1, Zhekov K.R.1, Burma N.G.1, Zvyagina G.A.1, Fil V.D.1, Gudim I.A.2 1B.Verkin Institute for Low Temperature Physics and Engineering of NAS of Ukraine, Kharkiv, Ukraine 2L.V. Kirensky Institute for Physics, Siberian Branch of the Russian Academy of Sciences, Krasnoyarsk, Russia Email: m.kolodyajnagmail.com In HoFe3(BO3)4 single crystals the main components of the tensor of the elastic moduli and the piezomodulus have measured. Spindependent contributions to the sound velocity, permittivity and piezoelectric response in the antiferromagnetic state are studied. The parameters of magnetoelectic and magnetoelastic interactions in the easyplane phase have determined. |
