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, … Websums of series, divisibility and powers of matrices. To include induction proofs for (i) summation of series e.g. show or show (ii) divisibility e.g. show is divisible by 4 (iii) matrix products e.g. show Students need to understand the concept of proof by induction and be able to apply it in a variety of contexts.
