Superconducting properties of a nanoparticle assembly of the organic conductor (TMTSF)2ClO4

Abstract

Resumen del trabajo presentado al APS March Meeting, celebrado en Baltimore, Maryland (USA) del 14 al 18 de marzo de 2016.While the study of thin-film and nanoparticle geometries on semiconductor devices, type-I elemental superconductors, and even single-molecular magnet materials have been explored, progress on thin-film and nanoparticle organic superconductors - in particular charge-transfer organic salts - has remained elusive. Recent refinements of synthesis conditions have produced nanoparticles of the Bechgaard salt (TMTSF)2ClO4. High resolution TEM studies have determined these nanoparticles are approximately 3-5 nm in size, which form nanoparticle clusters that are on average 34 nm in size. In order to investigate the properties of these nanoparticles, randomly oriented assemblies were studied in magnetic fields up to 16 T, using a high sensitivity inductive method in a dilution refrigerator, the results of which show that the ground-state properties of the nanoparticle assembly compares favorably with the bulk-single-crystal material.Peer reviewe
