Evidence of ratchet effect in nanowires of a conducting polymer
A. Rahman, M. K. Sanyal, R. Gangopadhayy +2
Ratchet effect, observed in many systems starting from living organism to artificially designed device, is a manifestation of motion in asymmetric potential. Here we report results…

Inversion of magnetoresistance in magnetic tunnel junctions : effect of pinhole nanocontacts
Soumik Mukhopadhyay, I. Das
Inverse magnetoresistance has been observed in magnetic tunnel junctions with pinhole nanocontacts over a broad temperature range. The tunnel magnetoresistance undergoes a change o…

Giant enhancement of room temperature magnetoresistance in La_{0.67}Sr_{0.33}MnO_{3}/Nd_{0.67}Sr_{0.33}MnO_{3} multilayers
Soumik Mukhopadhyay, I. Das
The metal-insulator transition temperature in CMR manganites has been altered and brought close to the room temperature by preparing LaSrMnO (LSMO)/ Nd$_{0.…
