In the last few years, Raman spectroscopy13,14,15,16,17 and electron transport measurements18, 19 have been performed on 2D magnets. Importantly, 2D ferromagnetism has been discovered very recently in two insulating vdW materials, Cr2Ge2Te620 and CrI321 and novel devices based on vdW ...
本步骤中由于fe容易氧化,fe和co熔点过高,要注意高温熔化的温度和氧压的控制。 在扫描电子显微镜(sem)、电子衍射能谱(eds)、拉曼光谱(raman)仪、x射线衍射光谱仪(xrd)的表征下,得到图2,图3,图4,图5以及图6的图像和数据。拉曼光谱的振动模式显示特征峰位于126cm-1、148cm-1,x射线衍射光谱表明样品很好的单晶特...
Here, by first﹑rinciples density functional theory calculations, the phonon vibrations and Raman intensities of Fe3GeTe2 are systematically studied from the bulk to monolayer structures. Furthermore, the spin﹑honon coupling effect is investigated by considering different interlayer magnetic orderings:...

the Raman-active E2g and A1g modes soften remarkably after an initial weak hardening and the peak widths of both modes broaden evidently on approaching Pc,followed by complete disappearance of both modes above this critical pressure.A possible underlying mechanism for such anomalous lattice softening...
