Magnetic Field‐Induced Quantum Critical Point in CeAuSb2

Published Web Location Commons 'BY' version 4.0 license

Transport, magnetic and thermal properties at high magnetic fields (H) and low temperatures (T) of the heavy fermion compound CeAuSb2 are reported. At H=0 this layered system exhibits antiferromagnetic order below TN = 6K. Applying B along the inter-plane direction, leads to a continuous suppression of TN and a quantum critical point at H c ≅ 5.4 T. Although it exhibits Fermi liquid behavior within the Neel phase, in the paramagnetic state the fluctuations associated with H c give rise to unconventional behavior in the resistivity (sub-linear in T) and to a TlnT dependence in the magnetic contribution to the specific heat. For H > Hc, and low T the electrical resistivity exhibits an unusual T3-dependence. © 2006 American Institute of Physics.
