Abstract

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.

层状 CrIr2Sn10 晶体中的室温以上铁磁性
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。
