Creation of 2D van der Waal materials on ferromagnetism at room temperature is important for practical application of their use. Recent studies indicate that metal interfacing pencils in ferromagnetism Fe3-xGeTe2 Causing nonzero magnetization at H ~ 300 k. However, the nanoscale nature of such experiments directly expresses structural and chemical changes. Here is a report sodium-interagated NaFe preparation2.78GeTe2 As well as investigate its structure and magnetic properties. Sodium is ready to intercometh into the van der Waals gap, as demonstrated by synchrotron X-ray diffraction. In parallel2.78GeTe2 The layer becomes chewed and chewed with chemical pressure, but maintains its structure and the temperature of ~ 140 k in ferromagnetic transition. However, we see a wide range of ferrimagnetic amorphous iron German impurity with a wide range of atmospheric conditions that leads to room temperature magnetization. This work emphasizes the importance of tension and electronic control for manipulating curve temperature in 2D ferromenes, and emphasizes phenomena firms in thyroid gland analysis.
