The resistivity below 1 K shows a deviation from Fermi liquid behavior described by a power law where the exponent ranges from 2 at x=0 to 1.6 for x = x_c. This suggests that a quantum phase transition (QPT) may exist near x_c associated with either the magnetic or superconducting transition temperature = 0 K. Transport for a sample with x = 0.004 < x_c has constant exponent of 1.77 as increasing pressure suppresses T_c to 0 K, suggesting that if a QPT exists it may be associated with the magnetic transition. | | Source: | arXiv, cond-mat/9908380 | | Services: | Forum | Review | PDF | Favorites | |
