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…
Drastic ground state changes induced by Ni substitution in NaxCoO2
N. Gayathri, M. Premila, A. Bharathi +3
We report on the effect of Ni substitution at the Co site on the physical properties of NaxCoO2 system by investigating the series NaxCo1-yNiyO2 (x=0.75, 0<y<0.15). An upturn in th…
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…
Mn Site Substitution Of La0.67Ca0.33MnO3 With Closed Shell Ions: Effect on Magnetic Transition Temperature
L. Seetha Lakshmi, V. Sridharan, D. V. Natarajan +2
Mn site is substituted with closed shell ions (Al, Ga. Ti, Zr and a certain combination of Zr and Al) and also with Fe and Ru ions carrying the magnetic moment (S=5/2 and 2 respect…
