|Title:||Mn-doped thiolated Au25 nanoclusters: Atomic configuration, magnetic properties, and a possible high-performance spin filter||Authors:||Zhou, M.
|Issue Date:||4-Apr-2011||Citation:||Zhou, M., Cai, Y.Q., Zeng, M.G., Zhang, C., Feng, Y.P. (2011-04-04). Mn-doped thiolated Au25 nanoclusters: Atomic configuration, magnetic properties, and a possible high-performance spin filter. Applied Physics Letters 98 (14) : -. ScholarBank@NUS Repository. https://doi.org/10.1063/1.3575203||Abstract:||We report an ab inito investigation on the ground-state atomic configuration, electronic structures, magnetic, and spin-dependent transport properties of Mn-doped Au25 nanoclusters protected by thiolate. It is found that the most stable dopant sites are near surfaces, rather than the center position of the nanoparticles. Transport calculations show that high- performance spin filters can be achieved by sandwiching these doped clusters between two nonmagnetic Au electrodes. The nearly perfect spin filtering originates from localized magnetic moments of these clusters that are well protected by ligands from the presence of electrodes. © 2011 American Institute of Physics.||Source Title:||Applied Physics Letters||URI:||http://scholarbank.nus.edu.sg/handle/10635/82704||ISSN:||00036951||DOI:||10.1063/1.3575203|
