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