Abstract
All the magnetoelectric properties of scheelite-type DyCrO4 are characterized by temperature- and fielddependent
magnetization, 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 a
large linear magnetoelectric effect with a considerable coupling coefficient. An applied electric field can induce
the converse linear magnetoelectric effect, realizing magnetic field control of ferroelectricity and electric field
control of magnetism. Furthermore, a higher magnetic field (>3 T) can cause a metamagnetic transition from the
initially collinear antiferromagnetic structure to a canted structure, generating a large ferromagnetic magnetization
up to 7.0 μB f.u.−1. Moreover, the new spin structure can break the space inversion symmetry, yielding ferroelectric
polarization, which leads to coupling of ferromagnetism and ferroelectricity with a large ferromagnetic
component.
