Structural and magnetic Properties of electrochemically grown Co-Fe and Ni-Fe alloy nanowire arrays

Pandya D.K., Kaur D., Chaudhary S., Kashyap S.C., IIT Delhi, IN

Magnetic nanowires are of immense importance in ultrahigh density magnetic storage media, micromagnetic sensors in read heads and spintronics devices. The nanowires of binary alloys of ferromagnetic metals like Co, Ni and Fe are particularly [...]

Growth and investigations on Fe/MgO/Fe magnetic tunnel junctions fabricated by dual ion beam sputtering technique

Singh B., Gupta P., Chaudhary S., Pandya D.K., Kashyap S.C., Inidan Institute of Technology Delhi, IN

The experimental observation of Tunnel Magnetoresistance (TMR) in 1996 by Moodera’s group of MIT has triggered intensive efforts worldwide to fabricate and investigate the magnetoresistive junctions showing a TMR effect. While in past 3-4 years, [...]

Magnetic properties of Sputter deposited and magnetically annealed IrMn/CoFeB nanometric bilayers for exchange biased magnetic tunnel junctions

Fulara H., Raju M., Chaudhary S., Kashyap S.C., Pandya D.K., Inidan Institute of Technology Delhi, IN

The work relates to the exploring the means of controlling the coercivities of the ferromagnetic thin films in a Magnetic Tunnel Junction Stack. Exchange bias route is a very powerful route in achieving this task. [...]
