- Summary
- Using the zero-field-muon-spin-relaxation (μSR) technique we have found clear evidence for antiferromagnetic ordering of Cu moments within the CuO planes of (Y{sub 1-x}Prₓ)Ba₂Cu₃O₇. The Neel temperatures are approximately 285 K, 220 K, 35 K, 30 K, and 20 K for x = 1, 0.8, 0.6, 0.58, and 0.54, respectively. For x = 0.50 we observe a fast-relaxing component of the muon polarization in addition to a long-time tail, reminiscent of spin-glass behavior. This region of the phase diagram (0.5≤x≤0.54) corresponds to the existence of both superconductivity and magnetism. The fully developed local magnetic field for x>0.54 is found to be ∼16 mT, but decreased to ∼12 mT at T = 17 K for the x = 1 sample, presumably due to the onset of Pr-ion ordering. Magnetic ordering also occurs in PrBa₂Cu₃O₆; the Neel temperature is ∼325 K. 7 refs., 4 figs.
