By high‐throughput screening Fe–Sn–Cr, (Fe,Cr)3Sn2 (Fe53.5Cr6.5Sn40) with high potential as new hard magnetic compound is discovered. To produce the compound in large amounts a special procedure is needed. By quantitative microscopy and magnetometry promising intrinsic properties, Js ～ 0.9 T, K1 ～ 1.7 MJ/m3, TC ～ 612 K, are found with K1 increasing with temperature.
We consider light ray reflections in a d-dimensional semi-infinite tube, for \(d\ge 3\), made of Lambertian material. The source of light is placed far away from the exit, and the light ray is assumed to reflect so that the distribution of the direction of reflected light ray has the density proportional to the cosine of the angle with the normal vector. We present new results on the exit distribution from the tube, and generalizations of some theorems from an earlier article, where the dimension was limited to the cases \(d=2\) and \(d=3\). 相似文献
