Resistive switching in ultra-thin La0.7Sr0.3MnO3 / SrRuO3 superlattices
S. Narayana Jammalamadaka, Johan Vanacken, V. V. Moshchalkov
Superlattices may play an important role in next generation electronic and spintronic devices if the key-challenge of the reading and writing data can be solved. This challenge eme…
Magnetocaloric effect and nature of magnetic transition in nanoscale Pr0.5Ca0.5MnO3
S. Narayana Jammalamadaka, S. S. Rao, S. V. Bhat +2
Systematic measurements pertinent to the magnetocaloric effect and nature of magnetic transition around the transition temperature are performed in the 10 nm Pr0.5Ca0.5MnO3 nanopar…
Dynamic response of exchange bias in graphene nanoribbons
S. Narayana Jammalamadakaa, S. S. Rao, J. Vanacken +3
The dynamics of magnetic hysteresis, including the training effect and the field sweep rate dependence of the exchange bias, is experimentally investigated in exchange-coupled pota…
Ferromagnetism in graphene nanoribbons: split versus oxidative unzipped ribbons
S. S. Rao, S. Narayana Jammalamadaka, A. Stesmans +5
Two types of graphene nanoribbons: (a) potassium-split graphene nanoribbons (GNRs), and (b) oxidative unzipped and chemically converted graphene nanoribbons (CCGNRs) were investiga…
Martensite-like transition and spin-glass behavior in nanocrystalline Pr0.5Ca0.5MnO3
S. Narayana Jammalamadaka, S. S. Rao, J. Vanacken +3
We report on isothermal pulsed (20 ms) field magnetization, temperature dependent AC - susceptibility, and the static low magnetic field measurements carried out on 10 nm sized Pr0…
Oscillatory exchange bias and training effects in nanocrystalline Pr0.5Ca0.5MnO3
S. Narayana Jammalamadaka, S. S. Rao, S. V. Bhat +2
We report on exchange bias effects in 10 nm particles of Pr0.5Ca0.5MnO3 which appear as a result of competing interactions between the ferromagnetic (FM)/anti-ferromagnetic (AFM) p…
