摘要: We have investigated the magnetic and electronic properties of a single-crystal HoB4. Antiferromagneticlike transitions were revealed by temperature-dependent magnetization exhibiting two transition temperatures at TN1=7.1 K TN2=5.7 K for an applied field along c-axis, showed only one T=5.7 K perpendicular to c-axis. The isothermal with c-axis exhibited three distinct metamagnetic phase Hc1=2 T, Hc2=3.5 T, Hc3=3.9 T T=2 K. On other hand, metamagneticlike transitions. A rapid change in temperature field-dependent resistivity was found be intimately correlated Based on both directions (H∥c H⊥c), anisotropic diagrams HoB4 const...
