Abstract

The term “multiferroics” was originally coined for materials in which multiple ferroic orders, such as <i>ferromagnetic</i>, <i>ferroelectric</i>, and <i>ferroelastic</i> orders, coexist simultaneously. In recent years, some classes of multiferroics where magnetic and ferroelectric orders coexist have been attracting much attention from both fundamental and technological points of view because the coupling between these two ferroic orders produces intriguing magnetoelectric and magnetodielectric phenomena. Here, we focus on a rare-earth zircon, DyVO<sub>4</sub>, which exhibits distinct magnetodielectric phenomena owing to another type of ferroic coupling. This compound combines two ferroic orders: “antiferroelectric order” and “quadrupolar order”. We discuss the effect of quadrupolar order (Jahn-Teller effect) on magnetic and dielectric properties in DyVO<sub>4</sub> in which the quadrupolar order of Dy 4<i>f</i> electrons induces the antiferroelectric order related to lattice distortion aroung V sites.
