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.2011http://zaguan.unizar.es/record/13172410.1103/PhysRevB.83.214426http://zaguan.unizar.es/record/131724oai:zaguan.unizar.es:131724info:eu-repo/grantAgreement/EUR/FP6/NMP-MAGMANET-515767info:eu-repo/grantAgreement/ES/MICINN/CSD2007-00010info:eu-repo/grantAgreement/ES/MICINN/MAT2007-61621info:eu-repo/grantAgreement/ES/MICINN/MAT2009-13977-C03Physical review.
