We report a study of magnetism and magnetic transitions of hexagonal single crystals by magnetization, specific heat, and heat transport measurements. Magnetization data show that the -axis magnetic field induces three magnetic transitions at 0.8, 12, and 28 T. The specific heat shows a peak at 2.2 K, which is due to a magnetic transition of moments. For low- thermal conductivity , a clear diplike feature appears in the isotherm at 1–1.25 T for , while in the case of , a steplike increase is observed at 0.5–0.8 T. The transition fields in are in good agreement with those obtained from magnetization, and the anomaly of can be understood by a spin-phonon scattering scenario. The natures of magnetic structures and corresponding field-induced transitions at low temperatures are discussed.
