Abstract: In this work, the magnetoelectric effect in a single-crystal substituted oxyferroborate crystal Sm$_{1-x}$La$_x$Fe$_3$(BO$_3$)$_4$ ($x$ = 0; 0.5; 0.75) was investigated. The data obtained in this experiment were compared with the data of the magnetostriction experiment. It was shown that magnetoelastic interaction is the cause of magnetoelectric interaction, but in this series of crystals there is a competing mechanism in the form of an increase in ion mobility, which affects the magnetoelectric properties, but does not affect the magnetostrictive ones.

Keywords: polarization, magnetostriction, substituted single crystal, magnetic anisotropy.
