Dilution of 2D antiferromagnetism by Mn site substitution in La{_1}Sr{_2}Mn{_{2-x}}Al{_x}O{_7}
Sunil Nair, A. Banerjee
We report the effect of Al substitution on the Mn site of the bilayered half doped manganite La{_1}Sr{_2}Mn{_2}O{_7}. This substitution dilutes the magnetically active Mn-O-Mn netw…
Effect of Al substitution on the charge ordered Pr{_0.5}Ca{_0.5}MnO{_3}: Structure, Magnetism and Transport
Sunil Nair, A. Banerjee
We report the effect of Mn site substitution of Al on the structural, magnetic and transport properties of charge ordered Pr{_0.5}Ca{_0.5}MnO{_3}. This substitution introduces impu…
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,…
Probing a ferromagnetic critical regime using nonlinear susceptibility
Sunil Nair, A. Banerjee
The second order para-ferromagnetic phase transition in a series of amorphous alloys (Fe{_5}Co{_{50}}Ni{_{17-x}}Cr{_x}B{_{16}}Si{_{12}}) is investigated using nonlinear susceptibil…
Observation of 3D Heisenberg-like ferromagnetism in single crystal La_{0.875}Sr_{0.125}MnO_3
Sunil Nair, A. Banerjee, A. V. Narlikar +2
We report measurements and analysis of the magnetic critical phenomena in a single crystal of LaSrMnO. The critical exponents associated with the ferr…
