  x Cu x compounds crystallize in a rhombohedral structure having R 3 ¯ m space group for x ≤ 0.75. Magnetic measurements were performed in the temperature range 4.2–900 K and external fields up to 7 T. The compounds are ferrimagnetically ordered. The Curie temperatures decrease from 509 K ( x = 0) up to 368 K ( x = 0.75). The cobalt moments, at 4.2 K, decrease gradually while effective cobalt moments

  The isothermal section of the phase diagram of the Tb-Dy-Co ternary system at 773 K was investigated by X-ray powder diffraction (XRD), differential thermal analysis (DTA) and scanning electron microscope (SEM). The result shows that this section consists of 9 single-phase regions and 8 two-phase regions, and no three-phase region. The compounds Tb2Co17 and Dy2Co17, Tb2Co7 and Dy2Co7, TbCo3 and DyCo3, TbCo2 and DyCo2, Tb4Co3 and Dy4Co3, Tb12Co7 and Dy12Co7. Tb3Co and Dy-3 CO form a continuous series of solid solutions. The single phases Th and Dy also form a continuous solid solution. The binary compounds TbCo5 and DyCo5 were not observed at 773 K. No ternary compound was found. In addition, we experimentally determined the vertical section of pseudobinary system and magnetic property of Tb1-xDyxCo2 (x from 0 to 1) series alloys, T-c decreases and the maximum magnetic entropy change |Delta S-M.max| increases with the increase of Dy content. The Arrott plots and the change of |Delta S-M.max| show that magnetic phase transition from second-order to first-order occurs with the increase of Dy content between x = 0.6 and 0.8.

  The isothermal section of the phase diagram of the Gd-Tb-Co ternary system at 500 degrees C was investigated by X-ray powder diffraction, differential thermal analysis and metallographic analysis techniques. In this isothermal section, there are nine single-phase regions, eight two-phase regions and none three-phase region. No ternary compound was found. The compounds Gd2Co17 and Th2Co17, Gd2Co7 and Tb2Co7, GdCo3 and TbCo3, GdCo2 and TbCo2, Gd4Co3 and Tb4Co3, Gd12Co7 and Tb12Co7, Gd3Co and Tb3Co, Gd and Tb form a continuous series of solid solutions. In addition, we experimentally determined the vertical section of pseudobinary system and the Curie temperature of Gd1-xTbxCo2 (x from 0 to 1) series alloys. (c) 2005 Elsevier B.V.

• Magnetic behaviour of γ-phase hydrides RCo3H∼4 in high magnetic fields

  High-field magnetization measurements have been carried out for single-crystal gamma-phase hydrides RCo3H(approximately 4) with R = Th and Dy and for powder samples with R = Nd and Gd. The results indicate that these gamma-phase hydrides with R = Y, Ho and Er become antiferromagnetic except for R = Gd at low temperatures due to the appearance of a negative Co-Co intersublattice interaction. A metamagnetic transition of the Co-sublattice magnetization occurs from the antiferromagnetic to the forced ferromagnetic state if the field is applied along the c-axis. GdCo3H(approximately 4), being ferrimagnetic at low temperatures, becomes antiferromagnetic above 32 K. The significant weakening of the R-Co interaction due to hydrogenation leads to a Neel temperature of about 200 K in all hydrides and an almost independent behaviour of the R and Co sublattices in the compounds with R = Nd, Ho and Er. The role of the R-Co interaction in the magnetic behaviour of the hydrides is discussed.
