Specific loss power was measured in alternating magnetic field of various amplitudes and at fixed frequency of 580.5¿kHz. Maximum SLP values acquired were 195¿W/g for Fe3O4/PEG200 and 60¿W/g for Fe3O4/PEG6000 samples. The samples were labeled as superparamagnetic by magnetization measurements, but SLP field dependence showed deviation from the behavior predicted by the commonly employed linear response theory. The scope of this theory for both samples with wide particle size distribution is discussed. Deviation from the expected behavior is explained by referring to polydisperse nature of the samples and field dependent relaxation rates. 000048132 540__ $$9info:eu-repo/semantics/openAccess$$aby-nc-nd$$uhttp://creativecommons.org/licenses/by-nc-nd/3.0/es/ 000048132 590__ $$a2.101$$b2015 000048132 591__ $$aPHYSICS, APPLIED$$b47 / 145 = 0.324$$c2015$$dQ2$$eT1 000048132 592__ $$a0.821$$b2015 000048132 593__ $$aPhysics and Astronomy (miscellaneous)$$c2015$$dQ2 000048132 655_4 $$ainfo:eu-repo/semantics/article$$vinfo:eu-repo/semantics/publishedVersion 000048132 700__ $$0(orcid)0000-0003-1558-9279$$aGoya, G.F.$$uUniversidad de Zaragoza 000048132 700__ $$aVranjes-Djuric, S. 000048132 700__ $$aJovic, N. 000048132 700__ $$aJancar, B. 000048132 700__ $$aAntic, B. 000048132 7102_ $$12003$$2395$$aUniversidad de Zaragoza$$bDpto.
