Magneto transport in (YxGd1-x)Co2 alloys near to magnetic phase boundary

We present experimental results on magnetotransport in (YxGd1-x)Co2 alloys, where the localized Gd-moments are coupled antiferromagnetically to the itinerant Co 3d electrons. The alloys are paramagnetic for x > 0.85. The transport properties of the paramagnetic alloys show Kondo like anomalies. O...

Zusammenfassung:We present experimental results on magnetotransport in (YxGd1-x)Co2 alloys, where the localized Gd-moments are coupled antiferromagnetically to the itinerant Co 3d electrons. The alloys are paramagnetic for x > 0.85. The transport properties of the paramagnetic alloys show Kondo like anomalies. On approaching to the magnetic phase boundary from the paramagnetic region the resistivity reveals non-Fermi liquid (NFL) behaviour, indicating a presence of apparently gap-less magnetic excitations.
