CRYSTAL-FIELD EXCITATION LINEWIDTHS IN (LN(X)Y(1-X))BA2CU3O7 (LN=ER, HO, TM)
PHYSICA C 235-240 (1994) 1707-1708
Abstract:
We have studied the temperature dependence of crystal field (CF) excitation linewidths of lanthanide ions (Er and Ho) in YBa(2)Cu(3)0(7) by neutron scattering. The Ho data reveal an anomaly in the CF damping around T-c with no evidence of a coherence peak below T-c. We have applied the theory of Becker, Fulde and Keller to derive the reduced s-f coupling constants from the CF linewidth data for the ions Er, Ho and Tm.MAGNETIC ORDER IN PRBA2CU3O6+X

Abstract:
We have studied the magnetic ordering of the Cu and Pr ions in PrBa2Cu3O6+x by neutron diffraction on single crystals with different oxygen contents. Two types of Cu ordering were observed, qualitatively similar to the anti-ferromagnetic phases reported in some studies of YBa2Cu3O6+x. A third magnetic structure was observed below 15K, which we believe corresponds to the magnetic ordering of the Pr sub-lattice.Magnetic-induction profile in a type-I superconductor by polarized-neutron reflectometry.
