摘要：

The temperature-magnetic field (T-H) phase diagram for the tetragonal compound CeRu2Al2B, determined from magnetization, specific heat, nuclear magnetic resonance (NMR), and electrical resistivity is reported. This system exhibits localized 4 f magnetic ordering at high temperatures where antiferromagnetism is observed at a Neel temperature T-N = 14.2 K and a first-order ferromagnetic transition is observed at a Curie temperature T-C = 12.8K. The application of a magnetic field H results in a rich phase diagram that includes three magnetically ordered phases: (1) antiferromagnetic, (2) canted antiferromagnetic, and (3) ferromagnetic, indicating that there are several finely tuned exchange interactions.
