Web1 Introduction. Transition metal dichalcogenides (TMDs) have been intensively studied for the variety of physical properties they offer. [1, 2] They are layered compounds with the formula MX 2, where M is a transition metal and X a chalcogen, characterized by weak, mostly van der Waals-like interactions between planes.According to the chalcogen … Web1 jan. 2005 · X-ray magnetic circular dichroism (XMCD) is the difference in absorption of left- and right-circularly polarized X-rays by a magnetized sample (Fig. 1) [1].Although MCD with X-rays is only about 15 years old, the physics is essentially the same as for the UV–vis MCD that has been known since 1897 [2].For (bio)inorganic chemists and materials scientists, …
