## Description

- description: The discovery of various primary ferroic phases in atomically-thin
    van der Waals (vdW) crystals have created a new two-dimensional (2D) wonderland
    for exploring and manipulating exotic quantum phases. It may also bring technical
    breakthroughs in device applications, as evident by prototype functionalities
    of giant tunnelling magnetoresistance, gate-tunable ferromagnetism and non-volatile
    ferroelectric memory etc. However, 2D multiferroics with effective magnetoelectric
    coupling (MEC), which ultimately decides the future of multiferroic-based information
    technology, has not been realized yet. Here, we show that an unconventional MEC
    mechanism interlocked with heterogeneous ferrielectric (FiE) transitions emerges
    at the 2D limit in vdW monolayers of CuCrP2S6 with inherent ferromagnetism and
    antiferroelectricity. Distinct from the homogeneous antiferroelectric (AFE) bulk,
    thin-layer CuCrP2S6 under external electric field makes layer-dependent heterogeneous
    FiE transitions, minimizing the depolarization effect introduced by the rearrangements
    of Cu+ ions within the ferromagnetic vdW cages of CrS6 and P2S6 octahedrons. The
    resulting FiE phases are characterized by substantially reduced interlayer magnetic
    coupling energy of nearly 50% with a moderate electric field of 0.3 V/nm, producing
    widely-tunable MEC which can be further engineered by asymmetrical electrode work
    functions.
