The knowledge of heating ability (magnetic losses) in AC magnetic field frequency function allows for selecting the optimal excitation. A hybrid system for the characterization of superparamagnetic nanoparticles was designed and tested. The proposed setup consists of an excitation coil and two sensing probes: calorimetric and magnetic. The measurements of the imaginary part of the complex magnetic susceptibility of superparamagnetic nanoparticles are possible in the kilohertz range. The system was verified using a set of nanoparticles with different diameters. The measurement procedure was described and verified. The results confirmed that an elaborated sensor system and measuring procedures could properly characterize the magnetic characteristics of nanoparticles. The main advantage of this system is the ability to compare both characteristics and confirm the selection of optimal excitation parameters.<\/jats:p>","DOI":"10.3390\/s22228879","type":"journal-article","created":{"date-parts":[[2022,11,17]],"date-time":"2022-11-17T06:24:42Z","timestamp":1668666282000},"page":"8879","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["The Hybrid System for the Magnetic Characterization of Superparamagnetic Nanoparticles"],"prefix":"10.3390","volume":"22","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-2449-0652","authenticated-orcid":false,"given":"Mateusz","family":"Midura","sequence":"first","affiliation":[{"name":"Institute of Radioelectronics and Multimedia Technology, Warsaw University of Technology, 00-655 Warsaw, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6713-9088","authenticated-orcid":false,"given":"Przemys\u0142aw","family":"Wr\u00f3blewski","sequence":"additional","affiliation":[{"name":"Institute of Radioelectronics and Multimedia Technology, Warsaw University of Technology, 00-655 Warsaw, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Damian","family":"Wanta","sequence":"additional","affiliation":[{"name":"Institute of Radioelectronics and Multimedia Technology, Warsaw University of Technology, 00-655 Warsaw, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0042-0473","authenticated-orcid":false,"given":"Jacek","family":"Kryszyn","sequence":"additional","affiliation":[{"name":"Institute of Radioelectronics and Multimedia Technology, Warsaw University of Technology, 00-655 Warsaw, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1524-5049","authenticated-orcid":false,"given":"Waldemar T.","family":"Smolik","sequence":"additional","affiliation":[{"name":"Institute of Radioelectronics and Multimedia Technology, Warsaw University of Technology, 00-655 Warsaw, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0204-2322","authenticated-orcid":false,"given":"Grzegorz","family":"Doma\u0144ski","sequence":"additional","affiliation":[{"name":"Institute of Radioelectronics and Multimedia Technology, Warsaw University of Technology, 00-655 Warsaw, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Micha\u0142","family":"Wieteska","sequence":"additional","affiliation":[{"name":"Institute of Radioelectronics and Multimedia Technology, Warsaw University of Technology, 00-655 Warsaw, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9004-555X","authenticated-orcid":false,"given":"Wojciech","family":"Obr\u0119bski","sequence":"additional","affiliation":[{"name":"Institute of Radioelectronics and Multimedia Technology, Warsaw University of Technology, 00-655 Warsaw, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ewa","family":"Pi\u0105tkowska-Janko","sequence":"additional","affiliation":[{"name":"Institute of Radioelectronics and Multimedia Technology, Warsaw University of Technology, 00-655 Warsaw, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Piotr","family":"Bogorodzki","sequence":"additional","affiliation":[{"name":"Institute of Radioelectronics and Multimedia Technology, Warsaw University of Technology, 00-655 Warsaw, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2022,11,17]]},"reference":[{"key":"ref_1","first-page":"179","article-title":"Magnetic particle imaging in vascular medicine","volume":"3","author":"Bakenecker","year":"2020","journal-title":"Innov.
