✦ Synopsis

A study of the magnetic properties of La2CUl_xZnxO4+ 8 (0<x<0.13; t5=0.02) by means of magnetization measurements (M vs. T, H) is reported. The N6el temperature of the 3D antiferromagnetic order (AF) is found to decrease with Zn substitution much more rapidly than in samples without excess oxygen. The effect of Zn substitution on the metamagnetic M vs. H transition is discussed, analyzing the temperature dependence of both the critical field H c and the weak ferromagnetic moment M s for different compositions x.

We have carried out extensive characterization and measurements on a high purity Y IBa2Cu408+d ( 124) sample. Metallographic investigations, X-ray diffraction and microprobe analysis have been performed and reveal a single phase with traces of CuO. Resistivity measurements give a resistivity ratio R
