S. L. Bud'ko, E. Q. T. Morosan, and P. C. Canfield
TL;DR
This study investigates the magnetic field effects on the electronic behavior of YbAgGe, revealing non-Fermi-liquid states induced by magnetic fields in a heavy fermion compound at very low temperatures.
Contribution
It provides detailed anisotropic resistivity and heat capacity measurements, establishing YbAgGe as a new heavy fermion compound with field-induced non-Fermi-liquid behavior.
Findings
Non-Fermi-liquid behavior observed above 45-70 kOe and 80-110 kOe for different field orientations.
YbAgGe exhibits two magnetic ordering temperatures below 1 K.
The compound is classified as a stoichiometric heavy fermion material.
Abstract
Detailed anisotropic resistivity and heat capacity measurements down to ~0.4 K and up to 140 kOe are reported for a single crystalline YbAgGe. Based on these data YbAgGe, a member of the hexagonal RAgGe series, can be classified as new, stoichiometric heavy fermion compound with two magnetic ordering temperatures below 1 K and field-induced non-Fermi-liquid behavior above 45-70 kOe and 80-110 kOe for $H || (ab) and H || c respectively.
