## Title

- title: Probing ultraweak in-plane magnetic anisotropy within a two-dimensional layered
    antiferromagnet
  title_type: original
  lang: en

## Description

- description: Magnetic anisotropy plays a crucial role in determining the critical
    behavior and phase transitions in two-dimensional magnetic systems. It is also
    required for the design of thin-film spintronic devices. Despite its significance,
    sensing extremely weak anisotropy has proven challenging in van der Waals antiferromagnetic/ferrimagnetic
    materials. Here, we first employ simulations of micro-magnetic energy function
    in few-layer easy-plane antiferromagnetic systems with a weak additional uniaxial
    anisotropy and unveil an intriguing even-odd effect closely linked to low-field
    spin-flop behaviors. We further perform tunneling magneto-conductance measurements
    on a model 2D antiferromagnetic insulator, CrCl3, exhibiting near-ideal easy-plane
    anisotropy. The magnetic field-controlled tunneling current at low temperature
    aligns well with simulated in-plane anisotropic spin-configuration, providing
    direct experimental evidence for detecting magnetic anisotropy field as weak as
    ~1 mT. Our work opens new avenues for finely characterizing magnetic structures
    and behaviors in 2D antiferromagnetic/ferrimagnetic systems, with potential applications
    in spintronics such as data storage and magnetic sensing.
