| Abstract: | We present Hall Effect and resistivity data which demonstrate that EuB6 is a degenerate semiconductor transforming into a metal or semimetal below the ferromagnetic ordering temperature, Tc = 13.7K. We also report an anomalously large, positive pressure dependence of Tc, (1/Tc)(ΔTc/ΔP) ? 4 × 10?2 kbar?1. |
