Abstract
The magnetic properties of the Zintl compounds EuZn2As2 and EuCd2Sb2 have been studied. The measurements of resistance, magnetic susceptibility and the ESR (X band) was performed in the range 4 - 300 K. The symmetric Eu2+ ESR lines had the g-factors 2.00 (EuZn2As2), 2.03 (EuCd2Sb2) and a Lorentzian shape above 120 K. The change of shape to Gaussian indicates on the magnetic fluctuations. EuZn2As2 and EuCd2Sb2 order antiferromagnetically with the TN 16.5 and 7.4 K, respectively; but with positive Curie-Weiss temperatures. The study revealed metallic conductivity for EuCd2Sb2 and semiconductor type for EuZn2As2. © Published under licence by IOP Publishing Ltd.
