Scaling Behavior of Angular Dependent Resistivity in CeCoIn₅: Possible Evidence for d-Wave Density Waves

الأصل · EN

In-plane angular dependent resistivity ADR was measured in the non-Fermi liquid regime of CeCoIn₅ single crystals at temperatures T ≤ 20 K and in magnetic fields H up to 14 T. Two scaling behaviors were identified in low field region where resistivity shows T-linear dependence, separated by a critical angle θc which is determined by the anisotropy of CeCoIn₅; i.e., ADR depends only on the perpendicular (parallel) field component below (above) θc. These scaling behaviors and other salient features of ADR are consistent with d-wave density waves.
