Electrical resistance of Ni nanowires (diameter greater than or equal to 20 nm) near the Curie Temperatures
M. Venkata Kamalakar, A. K. Raychaudhuri
In this letter we report electrical transport measurements on nickel nanowires of diameters down to 20 nm in the region close to its paramagnetic-ferromagnetic transition temperatu…
Effect of intrinsic instability of cantilevers on static mode Atomic Force Spectroscopy
Soma Das, P. A. Sreeram, A. K. Raychaudhuri
We show that the static force spectroscopy curve is significantly modified due to presence of intrinsic cantilever instability. This instability acts in tandem with such instabilit…
Hot electron effects and non-linear transport in hole doped manganites
Himanshu Jain, A. K. Raychaudhuri
We show that strong non--linear electron transport in the ferromagnetic insulating (FMI) state of manganites, responsible for phenomena such as colossal electroresistance and curre…
Size induced change-over from first to second order magnetic phase transition in La0.67Ca0.33MnO3 nanoparticles
Tapati Sarkar, A. K. Raychaudhuri
In this report we show that in the perovskite manganite La_{1-x}Ca_{x}MnO_3 for a fixed x \approx 0.33, the magnetic transition changes over from first order to second order on red…
