Abstract:	摘要： We report on experimental evidence of non- s -wave pairing in In and Sn nanoparticle assemblies. The superconducting transition temperature T C of the In and Sn nanoparticles varies noticeably with the particle diameter. Surprisingly, T C shifts to a noticeably higher temperature when magnetic Ni nanoparticles are introduced into the vicinity of the superconducting nanoparticles. The T C increases further when the magnetic Ni nanoparticles are brought even closer to the superconducting nanoparticles. There is a critical Ni composition and a critical spatial separation between the magnetic and superconducting nanoparticles that must be reached before their magnetic proximity will suppress the superconductivity. A qualitative mechanism is proposed to understand the present observations. 其他題名： J Nanopart Res 出版者： Dordrecht: Springer Netherlands 出版日期： 2013-06-01 出處： Journal of nanoparticle research : an interdisciplinary forum for nanoscale science and technology, 2013-06, Vol.15 (6), p.1-7, Article 1691 版權： Springer Science+Business Media Dordrecht 2013 版權： 2014 INIST-CNRS 識別號： ISSN: 1388-0764 識別號： EISSN: 1572-896X 識別號： DOI: 10.1007/s11051-013-1691-5
