Bulk ferromagnetism and large changes in photoluminescence intensity by magnetic field in -GaO
V. Sridharan, Sangam Banerjee, Manas Sardar +3
In this letter we report observation of room temperature ferromagnetism in bulk GaO . We also observe large (10-60%) increase/decrease in photoluminescence. In the red(700…
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.
Double metal-insulator transitions and magnetoresistance:An intrinsic feature of Ru substituted La(0.67)Ca(0.33)MnO(3)
L. Seetha Lakshmi, V. Sridharan, R. Rawat +4
In this paper, we examine the possible influence of extrinsic factors on the electrical and magnetotransport of La(0.67)Ca(0.33)Mn(1-x)Ru(x)O(3) (x < 0.10). These results not only…
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,…
