E. Brecht et al., ANTIFERROMAGNETIC ORDERING IN REDUCED AL DOPED YBA2CU3-XALXO6-CRYSTALS(DELTA SINGLE), Physica. C, Superconductivity, 235, 1994, pp. 871-872
In YBa2Cu3-AlxO6+delta single crystals antiferromagnetic AFII ordering
has been observed below 18 K by neutron diffraction. The transition t
emperature T-2 to the AFI ordering increases with x and delta.
