In HoFe3(BO3)4 single crystals the main components of the tensor of the elastic moduli and the piezomodulus have measured. Spin-dependent contributions to the sound velocity, permittivity and piezoelectric response in the antiferromagnetic state are studied. The parameters of magnetoelectic and magnetoelastic interactions in the easy-plane phase have determined. A phenomenological interpretation of the observed effects is given.
Key words: magnetoelectric, piezoelectric and magnetoelastic effects, multiferroics.
