We characterize the magnetic properties, exchange field, anisotropy field, and antiferromagnetic susceptibility of bulk akaganéite. In the nanoparticles, we find a drastic enhancement of the antiferromagnetic susceptibility, a phenomenon first predicted by Néel. Also, we find that akaganéite nanoparticles possess a thermoinduced magnetic moment. 000131724 536__ $$9info:eu-repo/grantAgreement/EUR/FP6/NMP-MAGMANET-515767$$9info:eu-repo/grantAgreement/ES/MICINN/CSD2007-00010$$9info:eu-repo/grantAgreement/ES/MICINN/MAT2007-61621$$9info:eu-repo/grantAgreement/ES/MICINN/MAT2009-13977-C03 000131724 540__ $$9info:eu-repo/semantics/openAccess$$aAll rights reserved$$uhttp://www.europeana.eu/rights/rr-f/ 000131724 590__ $$a3.691$$b2011 000131724 591__ $$aPHYSICS, CONDENSED MATTER$$b13 / 68 = 0.191$$c2011$$dQ1$$eT1 000131724 655_4 $$ainfo:eu-repo/semantics/article$$vinfo:eu-repo/semantics/publishedVersion 000131724 700__ $$0(orcid)0000-0001-6284-0521$$aLuis, F.$$uUniversidad de Zaragoza 000131724 700__ $$0(orcid)0000-0003-0828-3212$$aMillán, A.$$uUniversidad de Zaragoza 000131724 700__ $$0(orcid)0000-0003-2553-0633$$aNatividad, E.$$uUniversidad de Zaragoza 000131724 700__ $$0(orcid)0000-0002-6403-7270$$aPalacio, F. 000131724 700__ $$aKampert, E. 000131724 700__ $$aZeitler, U. 000131724 7102_ $$12003$$2395$$aUniversidad de Zaragoza$$bDpto.
