d-WAVE SYMMETRY IN Bi2212 AND Tl2223 VORTEX STATES: AN ME-mu SR STUDY

The vortex states of Bi2212 and Tl2223 have been studied by muon-spin resonance (mu SR). Similar to d-wave order predictions, and as recently found for M1237, twin-peak signatures in the main vortex signals have been observed at 5 kOe, below T/Tc = 0.8. The twin-peak splitting is proportional to {1-...

Zusammenfassung:The vortex states of Bi2212 and Tl2223 have been studied by muon-spin resonance (mu SR). Similar to d-wave order predictions, and as recently found for M1237, twin-peak signatures in the main vortex signals have been observed at 5 kOe, below T/Tc = 0.8. The twin-peak splitting is proportional to {1-(T/Tc)n}, with n about 3. 6 refs.
