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…
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…
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…
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…
