摘要: Antiferromagnetic ordering among Gd3+ ions in the nonsuperconducting compound TiBa2GdCu2O7-delta occurs near 2.2-2.3 K as confirmed by magnetic and calorimetric measurements. This compound is similar in structure to that of superconducting GdBa2Cu3O7-y, but with the Cu-O chains replaced by Tl-O planes, which also exhibits a similar magnetic transition at 2.2-2.3 K. This paper further compares the Neel temperatures and magnetic specific-heat anomalies of various Gd-containing compounds and related systems. Some common features between the compounds are discussed.
