Query: Diluted magnetism in Mn doped SrZnO2 single crystals   We have investigated the magnetic properties of Mn and Cu substituted SrZnO2
single crystals (SrZn0.99Mn0.01O2 and SrZn0.99Cu0.01O2). We observed signatures
of weak ferromagnetism as a sharp increase of magnetic susceptibility below 5 K
even in the low percentage (x= 0.01) of Mn substituted single crystals.
Magnetic susceptibility data measured parallel or perpendicular to the ab plane
yield anisotropic behavior with Curie Weiss temperature of about -320 K and
-410 K, respectively, suggesting the presence of strong antiferromagnetic
couplings among Mn atoms at high temperatures, similar to the Mn doped ZnO and
Fe doped BaTiO3 samples. In contrast, the SrZn0.99Cu0.01O2 crystal shows
paramagnetic behavior down to 2 K.
