Musfeldt and I. Swainson. Research Work at ORNL was sponsored by the Laboratory Directed Research and Development Program of ORNL, and was supported by the Scientific User Facilities Division Office of Basic Energy Sciences, DOE. A portion of this research was conducted at the Center for Nanophase Materials Sciences, which is sponsored at ORNL by the Office of Basic Energy Sciences, US DOE. 000015733 520__ $$aWe have performed unpolarized and polarized neutron diffraction experiments on monodisperse 8- and 13-nm antiferromagnetic MnO nanoparticles. For the 8-nm sample, the antiferromagnetic transition temperature T-N (114 K) is suppressed compared to that in the bulk material (119 K), while for the 13-nm sample T-N (120 K) is comparable to that in the bulk. The neutron diffraction data of the nanoparticles is well described using the bulk MnO magnetic structure but with a substantially reduced average magnetic moment of 4.2 +/- 0.3 mu(B)/Mn for the 8-nm sample and 3.9 +/- 0.2 mu(B)/Mn for the 13-nm sample. An analysis of the polarized neutron data on both samples shows that in an individual MnO nanoparticle about 80% of Mn ions order. These results can be explained by a structure in which the monodisperse nanoparticles studied here have a core that behaves similar to the bulk with a surface layer which does not contribute significantly to the magnetic order. 000015733 536__ $$0G:(DE-Juel1)FUEK412$$2G:(DE-HGF)$$aGrundlagen für zukünftige Informationstechnologien$$cP42$$x0 000015733 536__ $$0G:(DE-Juel1)FUEK415$$aGroßgeräte für die Forschung mit Photonen, Neutronen und Ionen (PNI)$$cP55$$x1 000015733 542__ $$2Crossref$$i2011-06-15$$uhttp://link.aps.org/licenses/aps-default-license 000015733 588__ $$aDataset connected to Web of Science 000015733 650_7 $$2WoSType$$aJ 000015733 65027 $$0V:(DE-MLZ)SciArea-170$$2V:(DE-HGF)$$aMagnetism$$x0 000015733 65017 $$0V:(DE-MLZ)GC-1604-2016$$2V:(DE-HGF)$$aMagnetic Materials$$x1 000015733 65017 $$0V:(DE-MLZ)GC-150-1$$2V:(DE-HGF)$$aKey Technologies$$x0 000015733 693__ $$0EXP:(DE-MLZ)DNS-20140101$$1EXP:(DE-MLZ)FRMII-20140101$$5EXP:(DE-MLZ)DNS-20140101$$6EXP:(DE-MLZ)NL6S-20140101$$aForschungs-Neutronenquelle Heinz Maier-Leibnitz$$eDNS: Diffuse scattering neutron time of flight spectrometer$$fNL6S$$x0 000015733 7001_ $$0P:(DE-HGF)0$$aBaker, S.N.$$b1 000015733 7001_ $$0P:(DE-HGF)0$$aLumsden, M.D.$$b2 000015733 7001_ $$0P:(DE-HGF)0$$aNagler, S.E.$$b3 000015733 7001_ $$0P:(DE-HGF)0$$aHeller, W.T.$$b4 000015733 7001_ $$0P:(DE-HGF)0$$aBaker, G.A.$$b5 000015733 7001_ $$0P:(DE-HGF)0$$aDeen, P.D.$$b6 000015733 7001_ $$0P:(DE-HGF)0$$aCranswick, L.M.D.$$b7 000015733 7001_ $$0P:(DE-Juel1)130991$$aSu, Y.$$b8$$uFZJ 000015733 7001_ $$0P:(DE-Juel1)VDB94929$$aChristianson, A.D.$$b9$$uFZJ 000015733 77318 $$2Crossref$$3journal-article$$a10.1103/physrevb.83.214418$$bAmerican Physical Society (APS)$$d2011-06-15$$n21$$p214418$$tPhysical Review B$$v83$$x1098-0121$$y2011 000015733 773__ $$0PERI:(DE-600)2844160-6$$a10.1103/PhysRevB.83.214418$$gVol. 83, p. 214418$$n21$$p214418$$q83<214418$$tPhysical review / B$$v83$$x1098-0121$$y2011 000015733 8567_ $$uhttp://dx.doi.org/10.1103/PhysRevB.83.214418 000015733 8564_ $$uhttps://juser.fz-juelich.de/record/15733/files/PhysRevB.83.214418.pdf$$yOpenAccess 000015733 8564_ $$uhttps://juser.fz-juelich.de/record/15733/files/PhysRevB.83.214418.gif?subformat=icon$$xicon$$yOpenAccess 000015733 8564_ $$uhttps://juser.fz-juelich.de/record/15733/files/PhysRevB.83.214418.jpg?subformat=icon-180$$xicon-180$$yOpenAccess 000015733 8564_ $$uhttps://juser.fz-juelich.de/record/15733/files/PhysRevB.83.214418.jpg?subformat=icon-700$$xicon-700$$yOpenAccess 000015733 8564_ $$uhttps://juser.fz-juelich.de/record/15733/files/PhysRevB.83.214418.pdf?subformat=pdfa$$xpdfa$$yOpenAccess 000015733 909CO $$ooai:juser.fz-juelich.de:15733$$pdnbdelivery$$pVDB$$popen_access$$pdriver$$pVDB:MLZ$$popenaire 000015733 9141_ $$y2011 000015733 915__ $$0LIC:(DE-HGF)APS-112012$$2HGFVOC$$aAmerican Physical Society Transfer of Copyright Agreement 000015733 915__ $$0StatID:(DE-HGF)0510$$2StatID$$aOpenAccess 000015733 915__ $$0StatID:(DE-HGF)0010$$aJCR/ISI refereed 000015733 9131_ $$0G:(DE-Juel1)FUEK412$$bSchlüsseltechnologien$$kP42$$lGrundlagen für zukünftige Informationstechnologien (FIT)$$vGrundlagen für zukünftige Informationstechnologien$$x0 000015733 9131_ $$0G:(DE-Juel1)FUEK415$$bStruktur der Materie$$kP55$$lGroßgeräteforschung mit Photonen, Neutronen und Ionen$$vGroßgeräte für die Forschung mit Photonen, Neutronen und Ionen (PNI)$$x1 000015733 9132_ $$0G:(DE-HGF)POF3-623$$1G:(DE-HGF)POF3-620$$2G:(DE-HGF)POF3-600$$aDE-HGF$$bForschungsbereich Materie$$lIn-house research on the structure, dynamics and function of matter$$vNeutrons for Research on Condensed Matter$$x0 000015733 9201_ $$0I:(DE-Juel1)PGI-4-20110106$$gPGI$$kPGI-4$$lStreumethoden$$x0 000015733 9201_ $$0I:(DE-Juel1)JCNS-FRM-II-20110218$$kJCNS (München) ; Jülich Centre for Neutron Science JCNS (München) ; JCNS-FRM-II$$lJCNS-FRM-II$$x1 000015733 9201_ $$0I:(DE-Juel1)JCNS-2-20110106$$gJCNS$$kJCNS-2$$lStreumethoden$$x2 000015733 970__ $$aVDB:(DE-Juel1)128974 000015733 9801_ $$aFullTexts 000015733 980__ $$aVDB 000015733 980__ $$aConvertedRecord 000015733 980__ $$ajournal 000015733 980__ $$aI:(DE-Juel1)PGI-4-20110106 000015733 980__ $$aI:(DE-Juel1)JCNS-FRM-II-20110218 000015733 980__ $$aI:(DE-Juel1)JCNS-2-20110106 000015733 980__ $$aUNRESTRICTED 000015733 981__ $$aI:(DE-Juel1)JCNS-2-20110106 000015733 981__ $$aI:(DE-Juel1)JCNS-FRM-II-20110218 000015733 981__ $$aI:(DE-Juel1)JCNS-2-20110106 000015733 999C5 $$1D.
