Recent progress of our pSR measurements on high-Tc and related systems is presented. Static magnetic order has been found and studied in LazCuO4, (L%-,Sr,)Cu04, YBa2Cu30,, YBa2 (Cu3-,Cox) 0 7 , as well as in B~~S T~Y C U~O~.NO magnetic order was found in the 3-dimensional systems BaBi03, Ba(Pbo.lBio.g) 0 3 , and (BaK) Bi03 above T = 10 K. The anisotropy of the magnetic field penetration depht X has been observed by using a c-axis alligned sintered pellet specimen of YBa2Cu307. The temperature dependence of All (for c 11 HQxt) indicates isotropic superconducting energy gap without any anomalies. Based on the muon spin relaxation rate a observed in (random) pellet specimens of various high-Tc superconductors, we found a linear relation between TC and a o: 1 1~~ o: ns/m', which suggests a high energy scale of superconducting coupling. Deviations from this linear relation are seen for samples with large carrier concentrations n..
C(p, p'7) C* (15.11 MeV) reaction. A polarized proton beam at 318 MeV was used and data were obtained for three mutually perpendicular directions of polarization. A scintillator hodoscope was used for detecting scattered protons and four BGO detectors for the 15.11-MeV y rays. Data are presented for eight azimuthal directions of the scattered protons around the beam direction, and for the polar angles averaged between 3. 3' and 11. 2'. The data are compared with both nonrelativistic and relativistic calculations. The average size of the asymmetries measured is somewhat less than both predictions and the results do not agree clearly with either prediction.PACS number(s): 25.40.Ep, 24.70.+s
