Effect of Ta(5+) Substitution on the Ground State of CMR Manganites
L. Seetha Lakshmi, K. Doerr, K. Nenkov +4
In this paper, we discuss the most deleterious effect of charge state modification at the Mn site on the ground state of the CMR manganites.
Ti substituted La(0.67)Ca(0.33)MnO(3) ortho-perovskites: Dominant role of local structure on the electrical transport and magnetic properties
L. Seetha Lakshmi, V. Sridharan, R. Rawat +1
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 structu…
Structure, Tranport and Magnetism of La(0.67)Ca(0.33)Mn(1-x)Ta(x)O(3)
L. Seetha Lakshmi, K. Doerr, K. Nenkov +3
For the first time,we report the effect of pentavalent subtitution at the Mn site of La(0.67)Ca(0.33)MnO(3). The ferromagnetic -metallic ground state modifies to a cluster-glass in…
Double metal-insulator transitions and MR in La(0.67)Ca(0.33)Mn(1-x)Ru(x)O(3) (x</=0.10): A qualitative understanding in light of possible magnetic phase separation
L. Seetha Lakshmi, V. Sridharan, D. V. Natarajan +5
This paper is in continuation of our previous work on the structural, electrical and magnetic properties of Ru doped La(0.67)Ca(0.33)MnO(3) compounds (Ref.: L.Seetha Lakshmi et.al,…
Universal behavior of transition temperatures Vs residual resistivity in Mn site doped La-Ca-Mn-O perovskites
L. Seetha Lakshmi, V. Sridharan, D. V. Natarajan +2
We discuss here a comparative study of the role of local structure and/or nature of local magnetic coupling on the electrical transport properties of Mn site substituted La-Ca-Mn-O…
Possible Magnetic separation in Ru doped La0.67Ca0.33MnO3
L. Seetha Lakshmi, V. Sridharan, D. V. Natarajan +5
X-ray diffraction, resistivity, ac susceptibility and magnetization studies on La0.67Ca0.33Mn1-xRuxO3 (0 x < 0.1) were carried out. A significant increase in the lattice parameters…
