摘要

层状铁磁（FM）材料对纳米自旋电子器件具有重要意义，然而，低转变温度和空气不稳定性仍然是层状 FM 化合物面临的主要挑战。在此，我们合成了层状晶体 CrIr2Sn10，其调频转变温度低于 315 K。此外，CrIr2Sn10 的磁性来自高度自旋极化的铬原子。CrIr2Sn10 将成为二维磁性和自旋电子器件的一个前景广阔的平台。

Above-room-temperature ferromagnetism in a layered CrIr2Sn10 crystal

Layered ferromagnetic (FM) materials are significant for nano-spintronic devices, however, low transition temperature and air instability remain major challenges for layered FM compounds. Herein, we have synthesized layered crystals CrIr₂Sn₁₀ with FM transition below 315 K. The ratio of the magnetization between in-plane and out-of-plane is 41. Moreover, the magnetism of CrIr₂Sn₁₀ is derived from the highly spin-polarized Cr atoms. CrIr₂Sn₁₀ will be a promising platform for 2D magnetism and spintronic devices.
