    1. Negative magnetoresistance (NMR) has unique performance in spintronics.

      CeCuAs2 is classified as a strong topological insulator in its paramagnetic state.

      CeCuAs2 exhibits large NMR beyond chiral anomaly, reaching -15% under 9 T at 2 K.

      A spin-glass-like state with Tf ~ 4.5 K hints possible spin-charge interaction.

      Tuning based on RE-Cu-As structural motif may provide new insights to explore NMR.

  • Large negative magnetoresistance (NMR), an important property for spintronics, requires experimental realization owing to the lack of suitable structural motifs. Herein, a remarkable NMR of up to -15% under 9 T at 2 K is demonstrated in a 112-type topological insulator candidate CeCuAs2 single crystal containing an As square net. Due to the presence of Dirac points coming from both the As square net and Ce–Cu–As layer in the paramagnetic state of CeCuAs2, the possibility of chiral anomaly is examined and eliminated by investigating magnetoresistance (MR) with different magnetic field configurations and angle-dependant MR, which show no specific restriction on the configurations under the applied magnetic fields. Upon investigation of the anisotropic magnetism, a spin-glass-like behavior with Tf ~ 4.5 K is observed in CeCuAs2, indicating that the large NMR could be attributed to the spin-dependent scattering induced by the possible spin-glass state. Hall resistivity exhibits a multiband feature and hole-dominated transport properties, corresponding well with the calculated band structure. This study not only offers a new building block for large NMR but also serves as a guide for the investigating the interplay among transport properties, topology, and magnetism, and it is expected to broaden the research on spintronics.
