C. Picard et P. Gerdanian, DETERMINATION OF THE NEEL TEMPERATURE IN YBA2CU3OZ BY ELECTRICAL-CONDUCTIVITY MEASUREMENTS, Solid state communications, 87(9), 1993, pp. 775-778
Experimental results are presented which show a coupling between the e
lectrical resistivity and the Neel transition which gives rise to a di
fferent experimental method for the T(N) determination in YBa2Cu3Oz. T
he results, T(N) vs. composition z, are compared to the limit between
the tetragonal (T) and the orthorhombic (O) phases, which confirms tha
t antiferromagnetism is independent of the lattice T or O symmetry.
