Presentation Transcript

    5. Ongoing questions: Behavior of different families of unconventional SCs? Cuprates Heavy fermion SCs Organic SCs Sr2RuO4 Fe pnictides etc. How do magnetism / magnetic fluctuations relate? Normal state behavior, M-I / structural links? Holy Grail: What is the comprehensive theory of unconventional superconductivity? Present Study

    6. Production of muons Protons extracted from cyclotron/synchrotron p + low Z production target ? ?+ + stuff ?+ ? ?+ + ?? parity violation: beam is spin polarized separate out positrons, etc. collimate / steer beam to sample Polarized muon sources: TRIUMF, Vancouver BC PSI, Switzerland ISIS, UK (pulsed) KEK, Japan (pulsed)

    25. Experiments Samples (Ca2-xSrx)2RuO4 x = 0.0, 0.2, 0.3, 0.5, 0.57, 0.65, 0.9, 1.0, 1.4, 1.5, 1.6, 1.8, 1.95 Sr2(Ru1-yTiy)O4 y = 0.01, 0.03, 0.05, 0.09 single xtals from Kyoto U. (Maeno et al. or Tsukuba (Yoshida et al. ZF- & LF-mSR: M20 (LAMPF) and/or M15 (DR) DC Susceptibility: ZFC, FC, H ~ 50-100 G
