 Abstract    Kenntnis von EuBeGd20 5 mit einem Beitrag über Phasen der Zusammensetzung M1 _xM'A .BeLn20 5 : Ca0,4Sr0,6BeSm2O5, Ba0,25Ca0,75BeNd2O5 und Ba0,36Sr0,64BeNd2O5 On E uB eG d20 5 and on Phases of the Composition M 1_^M'xBeLn20 5: Ca0,4Sr06BeSm2O 5, Bao,2sCao,75 BeNd2 0 5 and Ba0 3 6 Sr0,64BeNd2O5 Single crystals of (I): E uB eG d20 5, (II): Ca0,4Sr0ABeSm 20 5, (III): Ba0,25 Ca()75B eN d2O 5 and (IV): Ba<)3 6Sr()64B eN d2O s were prepared by (I): plasma torch and (II)-(IV): C 0 2-LASER technique. X-Rayo investigations lead to (I) monoclinic (space group C 2h-P2j/c, a = 7.126, b = 6.457, c = 9.394 A, ß = 90.40°) and (I I)-(I V) orthorhombic symmetry (D ^ -P n m a). (II: a = 9.454, b = 7.142, c = 6.490 A; III: a = 9.508, b = 7.188, c = 6.531 A; IV: a = 9.642, b = 7.295, c = 6.614 A). In contrary to the phases M j^ M '^ B eL ^ O s, E uBeG d2Os is characterized by an ordered distribution of Eu2+ and G d3+ inside o f the Kagome network.
