Spin glass behavior in A-site ordered YBaMn2O6 compound

Abstract

Magnetic properties of the A-site ordered YBaMn2O6 compound have been investigated by dc magnetic measurements. The divergence between zero-field-cooled and field-cooled susceptibilities at about 45 K suggests the presence of a spin-glass-like behavior. Thermal remnant magnetization, isothermal remnant magnetization, and memory effect measurements reveal the time relaxation of magnetization below 45 K, confirming the spin glass feature of the YBaMn2O6 sample. Detailed x-ray diffraction analysis demonstrates the existence of local antisite disorder on the ordered A sites, which might be the origin of the spin-glass behavior in the compound. © 2013 AIP Publishing LLC.
