A range of lanthanum strontium manganates (La 1−x Sr x MnO 3 -LSMO) where 0 ≤ x < 0.4 were prepared using a modified peroxide sol-gel synthesis method. The magnetic nanoparticle (MNP) clusters obtained for each of the materials were characterised using scanning electron microscopy (SEM), X-ray powder diffraction (XRD) and infra-red (IR) spectroscopy in order to confirm the crystalline phases, crystallite size and cluster morphology. The magnetic properties of the materials were assessed using the Superconducting quantum interference device (SQUID) to evaluate the magnetic susceptibility, Curie temperature (T c ) and static hysteretic losses. Induction heating experiments also provided an insight into the magnetocaloric effect for each material. The specific absorption rate (SAR) of the materials was evaluated experimentally and via numerical simulations. The magnetic properties and heating data were linked with the crystalline structure to make predictions with respect to the best LSMO composition for mild hyperthermia (41°C ≤ T ≤ 46°C). La 0.65 Sr 0.35 MnO 3 , with crystallite diameter of 82.4 nm, (agglomerate size of ∼10 μm), T c of 89°C and SAR of 56 W g Mn −1 at a concentration 10 mg mL −1 gave the optimal induction heating results (T max of 46.7°C)and was therefore deemed as most suitable for the purposes of mild hyperthermia, vide infra.CrystEngComm This journal is
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
