Title: Structural and magnetic properties of quasi-one-dimensional doped LiCuVO{sub 4}

The Neutron diffraction, X-ray photoemission and Magnetic properties of Zn, Co and Mn-doped LiCuVO{sub 4} were investigated. Both with Zn and Co doping the antiferromagnetic correlation increase. On the other hand Mn-doping induces the short range ferromagnetic ordering. Neutron diffraction study does not show any phase transition down to 5 K i.e., there is no indication of long range magnetic ordering. Neutron diffraction study also indicates that with Zn, Co and Mn doping the V–O lengths are changed. Maximum change in the V–O distances is observed for Mn-doped sample. On the other hand, X-ray photoemission spectroscopic data indicates Mn doping converts some Cu{sup 2+} ions into Cu{sup 3+} ions. - Graphical abstract: LiCuVO{sub 4} is a quasi-one-dimensional spin magnet. It shows antiferromagnetic ordering. It is observed when Mn is doped in the Cu site of LiCuVO{sub 4} a short range ferromagnetic ordering occurs. - Highlights: • LiCuVO{sub 4} is an one-dimensional spin chain system. • Mn ion is doped in Cu site to induce ferromagnetism. • Doping of Mn ion changes the Cu–O–Cu bond angle which in effect induces ferromagnetism.
