Antiferromagnetic Transition in Y 2 BaCuO 5

Magnetism of a compound Y 2 BaCuO 5 has been investigated by means of electron paramagnetic resonance (EPR) and static susceptibility measurements. An EPR absorption signal due to Cu 2+ was observed. The temperature dependence of the integrated signal intensity follows a Curie-Weiss law, consistent...

Description
Summary:Magnetism of a compound Y 2 BaCuO 5 has been investigated by means of electron paramagnetic resonance (EPR) and static susceptibility measurements. An EPR absorption signal due to Cu 2+ was observed. The temperature dependence of the integrated signal intensity follows a Curie-Weiss law, consistent with the results of static susceptibility. The Weiss temperature is -33±2 K. The EPR signal becomes appreciably broadened at low temperatures and disappears at about 20 K. This is indicative of an antiferromagnetic transition. A peak of static susceptibility is observed at 14 K.
