摘要:	摘要： An enhancement of the superconducting transition temperature and development of an additional magnetic component in the superconducting state, initiated by inhomogeneous spin anti-screening are demonstrated in In/Ni nanoparticle composites. A significant 9 % increase of the superconducting transition temperature as a consequence of the magnetic proximities is detected. Unconventional cross-shaped magnetization hysteresis loops appear in densely packed assemblies, where magnetization increases, rather than decreases, upon entering the superconducting state in field-decreasing loops. Surprisingly, magnetization in the superconducting state can reach values as large as 3.5 times the saturation magnetization revealed in the normal state. 其他題名： J Nanopart Res 出版者： Dordrecht: Springer Netherlands 出版日期： 2014-06 出處： Journal of nanoparticle research : an interdisciplinary forum for nanoscale science and technology, 2014-06, Vol.16 (6), p.1-7, Article 2447 版權： Springer Science+Business Media Dordrecht 2014 版權： 2015 INIST-CNRS 識別號： ISSN: 1388-0764 識別號： EISSN: 1572-896X 識別號： DOI: 10.1007/s11051-014-2447-6
