| Popis: | International audience; Electrical resistivity, magnetic susceptibility, and electron paramagnetic resonance measurements were carried out for cubic hexaboride KB6, which is one electron short of completely filling its conduction band. It is found that KB6 is not metallic and has localized spins. KB6 exhibits a highly unusual hysteresis in the magnetic susceptibility below 100 K, which suggests that it undergoes a slow relaxation process. |
