## Description

- description: A promising approach to the next generation of low-power, functional,
    and energy-efficient electronics relies on novel materials with coupled magnetic
    and electric degrees of freedom1–3. In particular, stripy antiferromagnets often
    exhibit broken crystal and magnetic symmetries4, 5 , which may bring about the
    magnetoelectric (ME) effect and enable the manipulation of intriguing proper-
    ties and functionalities by electrical means. The demand for expanding the boundaries
    of data storage and processing technologies has led to the development of spintronics
    toward two-dimensional (2D) platforms6,7. This work reports the ME effect in the
    2D stripy antiferromagnetic insulator CrOCl down to a single layer. By measuring
    the tunneling resistance of CrOCl on the parameter space of temperature, magnetic
    field, and applied voltage, we verified the ME coupling down to the 2D limit and
    unraveled its mechanism. Utilizing the multi-stable states and ME coupling at
    magnetic phase transitions, we realize multi-state data storage in the tunneling
    devices. Our work not only advances the fundamental understanding of spin-charge
    coupling but also demonstrates the great potential of 2D antiferromagnetic materials
    to deliver devices and circuits beyond the traditional binary operations.
