|Title:||Avoided Antiferromagnetic Order And Quantum Critical Point In Cecoin 5|
|Abstract:||The specific heat and resistivity of heavy fermion CeCoIn5 within the superconducting critical field of 5-9 T, in the field direction of , and at temperatures going down to 50 mK were measured. At 5 T critical field condition to the lowest temperatures, the results show a non-Fermi liquid (NFL) behavior. At above 8 T critical field conditions, the results exhibited a crossover behavior from that of a Fermi liquid (FL) to a non-Fermi liquid (NFL). The analysis study suggested that the NFL behavior was due to the antiferromagnetic (AFM) ordering in the Ce-based compound with the quantum critical point in the vicinity of superconducting critical field.|
