The complex superstructure in Mg1-xAlxB2 at x approximate to 0.5
Electron diffraction and high resolution microscopy have been performed on Mg1-xAlxB2 with x≅0.5. This composition displays a superstructure with a repeat period of exactly 2c along the c-axis and about 10 nm in the a-b plane. The superstructure results in ring-shaped superreflections in the diffrac...
