Ultra-narrow and widely tunable Mn^(2+) Emission from Single Nanocrystals of ZnS-CdS alloy
Abhijit Hazarika, Arunasish Layek, Suman De +5
Extensively studied Mn-doped semiconductor nanocrystals have invariably exhibited photoluminescence (PL) over a narrow energy window of width <= 149 meV in the orange-red region an…
Engineered spin-valve type magnetoresistance in FeO-CoFeO core-shell nanoparticles
P. Anil Kumar, Sugata Ray, S. Chakraverty +1
Naturally occurring spin-valve-type magnetoresistance (SVMR), recently observed in Sr2FeMoO6 samples, suggests the possibility of decoupling the maximal resistance from the coerciv…
Effect of "dipolar-biasing" on the tunability of tunneling magnetoresistance in transition metal oxide systems
P. Anil Kumar, D. D. Sarma
We observe an unusual tunneling magnetoresistance (TMR) phenomenon in a composite of LaSrMnO with CoFeO where the TMR versus applied magnetic fiel…
Magnetization in electron- and Mn- doped SrTiO3
D. Choudhury, B. Pal, A. Sharma +2
Mn-doped SrTiO_3.0, when synthesized free of impurities, is a paramagnetic insulator with interesting dielectric properties. Since delocalized charge carriers are known to promote…
Observation of magnetically hard grain boundaries in double-perovskite SrFeMoO
Y. Takahashi, V. K. Verma, G. Shibata +12
Unusual low temperature magneto-resistance (MR) of ferromagnetic SrFeMoO polycrystals has been attributed to magnetically hard grain boundaries which act as spin valves…
