Ti substituted La(0.67)Ca(0.33)MnO(3) ortho-perovskites: Dominant role of local structure on the electrical transport and magnetic properties

TL;DR

This study investigates how local structural changes, induced by Ti substitution, influence the electrical and magnetic behaviors of La(0.67)Ca(0.33)MnO(3), emphasizing the dominant role of local structure over spin interactions.

Contribution

It demonstrates that local structural effects are more influential than spin coupling in determining the properties of Ti-substituted LaCaMnO3 manganites.

Findings

Local structure significantly affects electrical transport.

Magnetic properties are primarily governed by local structural changes.

Ti substitution alters the ferromagnetic-metallic ground state.

Abstract

We discuss the effects of local structure on the electrical transport and magnetic properties of La(0.67)Ca(0.33)Mn(1-x)Ti(x)O(3) system.Based on the intercomparison of the structure, transport and magnetic properties of the Mn site substituted La(0.67)Ca(0.33)MnO(3) with isovalent diamagnetic and paramagnetic ions, we argue that local structural effects have a decisive role to play, compared to the local spin coupling effects, in the ferromagnetic-metallic ground state of the CMR manganites
