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…
The power law character of off-site power failures
A. John Arul, C. Senthil Kumar, S. Marimuthu +1
A study on the behavior of off-site AC power failure recovery times at three nuclear plant sites is presented. It is shown, that power law is appropriate for the representation of…
Tuning of the superconducting and ferromagnetic transitions by Cu doping for Ru in GdSr2RuCu2O8
J. Janaki, T. Geetha Kumary, R. Nagarajan +5
In order to explore the possibility of tuning superconducting and ferromagnetic transitions by Cu doping (for Ru) in GdSr2RuCu2O8, we have carried out synthesis and characterizatio…
