Abstract

Hole doped high-TC oxide of TlBa2 Y1-xCaxCu2Oy, Tl-1212, has been investigated by μ+ SR technique from an insulating to a superconducting (SC) region. Fast and slow precession components of the muon spin asymmetry which are due to an antiferromagnetic (AF) ordering of Cu-spins were observed from x=0 to x=0.5. The magnetic transition temperature (about 400 K) and local μ+ fields were found to have no x-dependence. No sign of the magnetic transition was observed for x=1.0 down to 1.8 K. The correlation between the AF ordered state and the SC state at the boundary of the two states (x=0.6) was examined.
