Unconventional magnetotransport in distorted square-net Eu₂InTe₅

We report the structural, magnetic, and electrical transport properties of the antiferromagnetic semiconductor Eu₂InTe₅. Single-crystal x-ray diffraction reveals an orthorhombic superstructure arising from distortions of the Te square-net layers, while the Eu sublattice remains close to an ideal square-net. Magnetization, resistivity, and heat capacity measurements confirm antiferromagnetic order at 7.3 K with uniaxial anisotropy and a spin-flop transition for fields along the c-axis. Electrical transport shows heavily doped semiconducting behavior with thermally activated carriers at high temperatures. Below approximately 80 K, we observe unconventional magnetoresistance and a nonlinear Hall response that evolve concomitantly, indicating a common origin. Finally, we discuss the underlying mechanisms that may give rise to the observed non-linear Hall response. These results identify Eu₂InTe₅ as a platform for exploring spin-charge coupling and correlated transport in square-net Eu-based materials.
