  We present the electron spin resonance study of the influence of an electric
field on the low-field multiferroic magnetic state in LiCuVO4. The shift of the
magnetic resonance spectra in the electric field has been observed
experimentally. Symmetry analysis has been conducted in order to describe the
static properties of the magnetic system. The low-frequency dynamics of LiCuVO4
in magnetic and electric fields was considered in the framework of hydrodynamic
approach. It was shown that the application of the external electric field
leads to the change of the configuration of the magnetic system before and
after spin-flop reorientation. Satisfactory agreement was obtained between the
results of experimental studies and theoretical consideration.
