Study of structural and magnetic properties of Gd_2MoO_6 compound

摘要

In this present work, we study the structural, microstructural, electronic and magnetic properties of Gadolinium Molybdate (Gd_2MoO_6) compound synthesized via solid statereactionmethod. The single-phase nature of the compound is confirmed using x-ray diffraction (XRD) technique and the structure is refined to monoclinic symmetry (C2/c, Space group 15). Surface imaging of the sample shows agranular type morphology of about 0.1 μm. X-ray photoelectron spectroscopic measurements reveal mixed valent (4+/6+) charge states in case of Mo and also the presence of oxygen vacancies in Gd_2MoO_6. Magnetization measurements performed using 7T SQUID VSM reveal an overall antiferromagnetic behavior.
