Critical behavior of ferromagnetic pure and random diluted nanoparticles with competing interactions: variational and Monte Carlo approaches
Critical behavior of ferromagnetic pure random diluted nanoparticles interactions: variational
2010/11/23
The magnetic properties and critical behavior of both ferromagnetic pure and metallic nanopar-
ticles having concurrently atomic disorder, dilution and competing interactions, are studied in the fram...
Conduction of DNA molecules attached to a disconnected array of metallic Ga nanoparticles
Conduction of DNA molecules disconnected array of metallic Ga nanoparticles
