AB All the magnetoelectric properties of scheelite-type DyCrO4 are characterized by temperature- and fielddependentmagnetization, specific heat, permittivity, electric polarization, and neutron diffraction measurements.Upon application of a magnetic field within ±3 T, the nonpolar collinear antiferromagnetic structure leads to alarge linear magnetoelectric effect with a considerable coupling coefficient. An applied electric field can inducethe converse linear magnetoelectric effect, realizing magnetic field control of ferroelectricity and electric fieldcontrol of magnetism. Furthermore, a higher magnetic field (>3 T) can cause a metamagnetic transition from theinitially collinear antiferromagnetic structure to a canted structure, generating a large ferromagnetic magnetizationup to 7.0 μB f.u.−1. Moreover, the new spin structure can break the space inversion symmetry, yielding ferroelectricpolarization, which leads to coupling of ferromagnetism and ferroelectricity with a large ferromagneticcomponent.
