Magnetoresistance thesis

magnetoresistance thesis Spin-dependent electron transport behaviors were systemically studied in these devices by varying the pvdf film thickness from 3 layers (7 nm) to 13 layers (30 nm) with increasing pvdf layer numbers, the magnetoresistance (mr) response decreases likely due to the change in spin transport from tunneling to hopping.

Different topics related to spin transfer during the years of my phd research in prof kent's group at nyu and also in a collaboration with the ibm t j watson research center this thesis describes the projects that i have worked on these years here i start with the giant magnetoresistance effect 11 giant magnetoresistance.
