Millimeter-size crystals of AlSr 2 YCu 2 O 7 were synthesized by the 6ux method in alumina crucibles. Di4erent mixtures of SrO : CuO (ranging from 25 : 75 to 12 : 88 mol ratio) were used as 6ux. No aluminum was added to the reagents. Depending on the 6ux composition and cooling rate, crystals di4ere
After crystals of \(\mathrm{CuNd}_{2} \mathrm{Ge}_{2} \mathrm{O}_{8}\) are grown using \(\mathrm{CuO}\) as self flux, the crystal structure is determined by single-crystal X-ray diffraction in the space group \(\mathrm{Cm}\) (No. 8) to an \(R\) value of \(5.1 \%\). It is monoclinic, with \(a=9.846(2
