Superconductivity
Research from A. Ballestar and co-authors yields new data on superconductivity
December 2nd, 2009
"A new 2D intergranular semiconducting-magnetic material obtained by depositing magnetic clusters of permalloy in a doped Si surface, is presented. The material, exhibiting ohmic contacts, has an ample range of properties and versatility by simply controlling deposition time," researchers in Madrid, Spain report. "We can have clusters separated by relatively large, intermediate distances or a continuous film. This permits to study the magnetic and electrical properties of the clusters mediated by currents through the n-doped Si. We observe anisotropic and giant magnetoresistances of and between clusters. Also, by preventing oxidation of the Si surface, we suggest the...
