We have grown single crystals of Fe1+dTe by a conventional self-flux method. We obtained plate-like single crystals with dnom \geq 0.1. The value of the magnetization increased with increasing excess Fe concentration, and a broadening of…

Single crystals of Fe-substituted Cu2Mn1-xFexBO5 ludwigites have been synthesized using flux technique (x=0.2, 0.4, 0.5 - in the initial flux system). Structural properties of the synthesized compounds were studied by the single crystal and…

Single crystals of (Nd1-xCex)2Fe14B are grown out of Fe-(Nd,Ce) flux. Chemical and structural analysis of the crystals indicates that (Nd1-xCex)2Fe14B forms a solid solution until at least x = 0.38 with a Vegard-like variation of the…
