dc.description.abstractEnComposite nanoparticles with variable ratios of M-type Sr-hexaferrite and maghemite phases were prepared via the sol–gel method employing polyvinylalcohol as the stabilizing agent, followed by thermal treatment at 600 °C for 32–190 min. The measurements in static magnetic field revealed considerable variation of the coercivity and remanence depending on the relative content of the highly magnetically anisotropic Sr-hexaferrite phase. Calorimetric heating experiments were carried out on aqueous gel suspensions under an alternating magnetic field of maximum amplitude Hmax = 15.1–68.4 kA m-1 and frequency ν = 108 kHz. They showed a strong dependence of the heating efficiency on the coercivity and remanence of the composites, with a specific absorption rate (SAR) value ranging from units to tens of W/g(Feferrimagnetic).
