Influence of oxygen ion implantation on magnetic microstructure in Pt/Co/Pt multilayers with perpendicular magnetic anisotropy
Anmol Sharma, Mukul Gupta, Prasanta Karmakar +7
The interaction of oxygen with cobalt and cobalt-based alloys has been a very important topic in the field of spintronics as it leads to enhanced orbital anisotropy and interfacial…
Measurement of the Hoyle State Radiative Transition Width
T. K. Rana, Deepak Pandit, S. Manna +30
The radiative decay of the Hoyle state is the doorway to the production of heavier elements in stellar environment. Here we report, an exclusive measurement of electric quadruple (…
Evolution of magnetic anisotropy in cobalt film on nanopatterned silicon substrate studied in situ using MOKE
Khushboo Bukharia, Prasanta Karmakar, Dileep Kumar +1
Evolution of magnetization behaviour of cobalt film on nano patterned silicon substrate, with film thickness, has been studied. In situ magneto-optical Kerr effect measurements dur…
Impurity in low energy Ar+ ion beam is the cause of pattern formation on Si
Dipak Bhowmik, Manabendra Mukherjee, Prasanta Karmakar
We report the decisive role of reactive ion impurities in low energy Ar+ ion beam on surface nanopattern formation. The source of experimental inconsistency in pattern formation by…
Inhomogeneous Charge Distribution Across Gold Nanoclusters Measured by Scattered Low Energy Alkali Ions
Christopher Salvo, Prasanta Karmakar, Jory Yarmoff
The neutralization of low energy Na and Li ions scattered from Au nanoclusters formed by deposition onto oxide surfaces decreases as the cluster size increases. An explanat…
Large area buried nanopatterning by broad ion implantation without any mask or direct writing
Prasanta Karmakar, Biswarup Satpati
We have introduced here a simple, single step and cost effective broad ion beam technique for preparation of nanoscale electronic, magnetic, optical and mechanical devices without…
