Abstract

We measured electrical resistivity under magnetic field ( < 13.5 T ) and pressure ( < 3 GPa ) in Ce 3 Al 11 to study anomalies at 3.2 and 6.3 K in zero field and ambient pressure. Transverse magnetoresistance shows that Ce 3 Al 11 behaves like a standard Kondo material after the two anomalies disappear. With applied pressure, the low-temperature anomaly moves down to lower temperature very rapidly. After the low-temperature anomaly is suppressed, high-temperature anomaly still stands at almost the same temperature (6.3 K). Ce 3 Al 11 behaves like a ferromagnet with Kondo behavior from the stand point of electrical resistivity under pressure.
