Static magnetic response of clusters in Co_{0.2}Zn_{0.8}Fe_{1.95}Ho_{0.05}O_{4} spinel oxide
R. N. Bhowmik, R. Ranganathan, R. Nagarajan
Earlier investigation of Co_{0.2}Zn_{0.8}Fe_{1.95}Ho_{0.05}O_{4} spinel has shown the existence of "super-ferromagnetic " clusters containing Fe^{3+} and Ho^{3+} ions along with sm…

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…

Particle size effects in the antiferromagnetic spinel CoRhO
R. N. Bhowmik, R. Nagarajan, R. Ranganathan
We report the particle size dependent magnetic behaviour in the antiferromagnetic spinel CoRh2O4. The nanoparticles were obtained by mechanical milling of bulk material, prepared u…
