Resistance fluctuations and 1/f noise in single crystalline Ni nanowires
Sudeshna Samanta, M. Venkata Kamalakar, A. K. Raychaudhuri
We measured the low frequency (10mHz < f < 10Hz) resistance fluctuations (Noise) in single crystalline ferromagnetic Ni nanowires (diameter ~35nm) in the temperature range 80K-300K…

Temperature dependent electrical resistivity of a single strand of ferromagnetic single crystalline nanowire
M. Venkata Kamalakar, A. K. Raychaudhuri, Xueyong Wei +2
We have measured the electrical resistivity of a single strand of a ferromagnetic Ni nanowire of diameter 55 nm using a 4-probe method in the temperature range 3 K-300 K. The wire…

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…
