Description
The authors report on investigations into the impact of the rare earths (RE) as given in the title on the ceramic microstructure and the critical current density jc in the superconductor system REBa2Cu3Ox. With RE = Sm, Eu, or Gd, the material is homogeneous in phase and crystallizes in platelets with maximum sizes of up to 350 μm. Material with RE = Y, Dy, or Ho exhibits grain sizes up to 500 μm, and a low amount of phase inhomogeneities. The critical currents measured are between 25 Acm-2 and 290 Acm-2 at 77 K, without external field. The highest values are found in systems with RE = Eu or Gd. (orig.)
Abstract (German)
Im System REBa2Cu3Ox wurde der Einfluss verschiedener seltener Erden RE = Y, Sm, Eu, Gd, Dy und Ho auf das keramische Gefuege und die kritische Stromdichte jc untersucht. Fuer RE = Sm, Eu und Gd sind die Verbindungen phasenrein und kristallisieren in Plattenform mit maximalen Abmessungen bis zu 350 μm. RE = Y, Dy und Ho erreichen Korngroessen bis 500 μm bei einem geringen Anteil an Fremdphasen. Die kritischen Stromdichten lagen im Bereich von 25 Acm-2 bis 290 Acm-2 bei 77 K ohne aeusseres Feld. Die hoechsten Werte wurden fuer RE = Eu und Gd erreicht. (orig.)Additional details
