Chemical Disorder-DrivenCluster Spin Glass in PseudobinaryCo<sub>2</sub>Zn<sub>10.2</sub>Mn<sub>0.8</sub>: An Experimental andTheoretical Study
The investigation focuses on Mn substitution in Co<sub>2</sub>Zn<sub>11</sub>, prepared by pursuing a solid-state sealed tube method under high vacuum. We report the crystal structure and magnetic properties of Co<sub>2</sub>Zn<sub>10.2</sub>Mn<sub>0.8</sub> in detail. Co<sub>2</sub>Zn<sub>10.2</sub>Mn<sub>0.8</sub> adopts the noncentrosymmetric space group <i>I</i>4̅3<i>m</i> (No. 217), and the distribution of Co, Mn, and Zn atoms is confirmed using X-ray and neutron powder diffraction (NPD) techniques. The magnetic studies reveal cluster glass (CG) formation below the spin-freezing temperature of 23.1 K in Co<sub>2</sub>Zn<sub>10.2</sub>Mn<sub>0.8</sub>, also indicated by the large value of the characteristic relaxation time (τ<sub>0</sub>) of ∼10<sup>–8</sup> s. This large value of τ<sub>0</sub> supports the formation of magnetic clusters. The magnetic moment primarily originates due to the spins of Mn atoms, which is realized from significant differences between majority- and minority-spin channels of Mn 3d states in the projected density of states curves.
