Electron probe microanalysis of Mg–B compounds: stoichiometry and heterogeneity of superconductors
The cover picture of the present issue of physica status solidi (a) is a false-colour representation of the back-scattered electron image from the surface of MgB12 (sample 2 of Ref. ). It shows the heterogeneity of the magnesium boride grains in the synthesized powders. The red colour approximately corresponds to the MgB12 phase and orange to the MgB7 phase, respectively; the yellow dots are holes in the sample.
