In the case of ferritin, we show that the time dependence of the magnetization also depends on the maximum and previous cooling fields. This behavior is associated to changes in the intraparticle energy barriers imprinted by these fields. Accordingly, the dependence of the coercive and loop-shift fields with the maximum field in ferritin and ferrihydrite can be described within the frame of a uniform-rotation model considering a dependence of the energy barrier with the maximum and the cooling fields. 000132258 536__ $$9info:eu-repo/grantAgreement/ES/MICINN/CSD2006-00012$$9info:eu-repo/grantAgreement/ES/MICINN/CSD2007-00010$$9info:eu-repo/grantAgreement/ES/MICINN/MAT2007-61621$$9info:eu-repo/grantAgreement/ES/MICINN/MAT2009-08667 000132258 540__ $$9info:eu-repo/semantics/openAccess$$aAll rights reserved$$uhttp://www.europeana.eu/rights/rr-f/ 000132258 590__ $$a3.691$$b2011 000132258 591__ $$aPHYSICS, CONDENSED MATTER$$b13 / 68 = 0.191$$c2011$$dQ1$$eT1 000132258 655_4 $$ainfo:eu-repo/semantics/article$$vinfo:eu-repo/semantics/publishedVersion 000132258 700__ $$aAmaral,V.
