In this work, a new quasi-1D vdW layered compound CrZr4Te14 was successfully synthesized. The crystals show strong anisotropy in terms of phonon vibrations, electrical transport, and magnetism. Notably, a large intrinsic negative magnetoresistance (nMR) effect was achieved, making CrZr4Te14 an interesting platform for exploring novel polarization-sensitive spintronics.
The discovery of 2D van der Waals (vdW) magnetic materials is of great significance to explore intriguing 2D magnetic physics and develop innovative spintronic devices. In this work, a new quasi-1D vdW layered compound CrZr4Te14 is successfully synthesized. Owing to the existence of 1D [CrTe2] and [ZrTe3] chains along the b-axis, CrZr4Te14 crystals show strong anisotropy of phonon vibrations, electrical transport, and magnetism. Density functional theory calculations reveal the ferromagnetic (FM) coupling within the [CrTe2] chain, while the interchain and interlayer couplings are both weakly antiferromagnetic (AF). Notably, a large intrinsic negative magnetoresistance (nMR) of -56% is achieved at 2 K under 9 T, and the in-plane anisotropic factor of nMR can reach up to 8.2 in the CrZr4Te14 device. The 1D FM chains and anisotropic nMR effect make CrZr4Te14 an interesting platform for exploring novel polarization-sensitive spintronics.
