The interaction between Co and Mn ions on the magnetic frustration and the inducement of the double-exchange mechanism in hole-doped La0.6 Dy0.1 Ca0.3 Co1-x MnxO3 (x = 0–1.0) cobaltite

This study investigates the interaction between Co and Mn ions on spin state behaviour and magnetic frustration in hole-doped La0.6Dy0.1Ca0.3Co1-x MnxO3 (x = 0–1.0) cobaltite. It aims to understand the inducement of the double-exchange (DE) mechanism in this system. The samples were synthesised usin...

This study investigates the interaction between Co and Mn ions on spin state behaviour and magnetic frustration in hole-doped La0.6Dy0.1Ca0.3Co1-x MnxO3 (x = 0–1.0) cobaltite. It aims to understand the inducement of the double-exchange (DE) mechanism in this system. The samples were synthesised using the conventional solid-state synthesis method, and their crystal structure and magnetic properties were analysed. Rietveld refinement of X-ray diffraction data confirmed that La0.6Dy0.1Ca0.3Co1-x O3 (x = 0.0 and 0.2) samples had rhombohedral crystals structure with R3− c space group. An orthorhombic (Pbnm) perovskite structure was observed for the La0.6Dy0.1Ca0.3Co1-x MnxO3 (x = 0.4 –1.0) accompanied by increasing cell volume in the samples as the substitution level of Mn increases. Temperature dependence of resistivity ρ (T) shows semiconducting behaviour in the whole temperature and composition range of x = 0.0–0.8. However, further substitution with x = 0.9 and x = 1.0 give remarkable induced MI behaviour where the MI transition temperature (TMI) increased from 75 K and 132 K, respectively. The result suggests that Mn ions play an important role in the magnetic properties of the cobaltite, and the system can be tuned by adjusting the Mn concentration. © 2023, S.C.
