The aim of this work is to understand the dependence of the heating power with the nanoparticle (NP) mean size, for the manganite composition La0.75Sr0.25MnO3 (LSMO)\u2014the one with maximum critical temperature for the whole La\/Sr ratio of the series. We have prepared four different samples, each one annealed at different temperatures, in order to produce different mean NP sizes, ranging from 26 nm up to 106 nm. Magnetization measurements revealed a FC-ZFC irreversibility and from the coercive field as function of temperature we determined the blocking temperature. A phase diagram was delivered as a function of the NP mean size and, based on this, the heating mechanism understood. Small NPs (26 nm) is heated up within the paramagnetic range of temperature (T&gt;Tc), and therefore provide low heating efficiency; while bigger NPs are heated up, from room temperature, within the magnetically blocked range of temperature (T&lt;TB), and also provide a small heating efficiency. The main finding of this article is related with the heating process for NPs within the magnetically unblocked range of temperature (Tc&gt;T&gt;TB), for intermediate mean diameter size of 37 nm, with maximum efficiency of heat transfer.<\/jats:p>","DOI":"10.3390\/nano11071826","type":"journal-article","created":{"date-parts":[[2021,7,14]],"date-time":"2021-07-14T21:56:51Z","timestamp":1626299811000},"page":"1826","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":33,"title":["Understanding the Dependence of Nanoparticles Magnetothermal Properties on Their Size for Hyperthermia Applications: A Case Study for La-Sr Manganites"],"prefix":"10.3390","volume":"11","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-9429-7970","authenticated-orcid":false,"given":"Mylla C.","family":"Ferreira","sequence":"first","affiliation":[{"name":"Institute of Physics, Fluminense Federal University, Niter\u00f3i 24210-346, RJ, Brazil"}]},{"given":"Bruno","family":"Pimentel","sequence":"additional","affiliation":[{"name":"Institute of Physics, Fluminense Federal University, Niter\u00f3i 24210-346, RJ, Brazil"}]},{"given":"Vivian","family":"Andrade","sequence":"additional","affiliation":[{"name":"IFIMUP\u2014Institute of Physics for Advanced Materials, Nanotechnology and Photonics of University of Porto, 4169-007 Porto, Portugal"},{"name":"\u201dGleb Wataghin\u201d Physics Institute, State University of Campinas, Campinas 13083-859, SP, Brazil"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6977-2143","authenticated-orcid":false,"given":"Vladimir","family":"Zverev","sequence":"additional","affiliation":[{"name":"Faculty of Physics, Moscow State University, 119991 Moscow, Russia"}]},{"given":"Radel R.","family":"Gimaev","sequence":"additional","affiliation":[{"name":"Faculty of Physics, Moscow State University, 119991 Moscow, Russia"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4087-3474","authenticated-orcid":false,"given":"Andrei S.","family":"Pomorov","sequence":"additional","affiliation":[{"name":"Faculty of Physics, Moscow State University, 119991 Moscow, Russia"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0558-9398","authenticated-orcid":false,"given":"Alexander","family":"Pyatakov","sequence":"additional","affiliation":[{"name":"Faculty of Physics, Moscow State University, 119991 Moscow, Russia"}]},{"given":"Yulia","family":"Alekhina","sequence":"additional","affiliation":[{"name":"Faculty of Physics, Moscow State University, 119991 Moscow, Russia"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4319-3781","authenticated-orcid":false,"given":"Aleksei","family":"Komlev","sequence":"additional","affiliation":[{"name":"Faculty of Physics, Moscow State University, 119991 Moscow, Russia"}]},{"given":"Liudmila","family":"Makarova","sequence":"additional","affiliation":[{"name":"Faculty of Physics, Moscow State University, 119991 Moscow, Russia"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0757-4942","authenticated-orcid":false,"given":"Nikolai","family":"Perov","sequence":"additional","affiliation":[{"name":"Faculty of Physics, Moscow State University, 119991 Moscow, Russia"}]},{"given":"Mario S.","family":"Reis","sequence":"additional","affiliation":[{"name":"Institute of Physics, Fluminense Federal University, Niter\u00f3i 24210-346, RJ, Brazil"}]}],"member":"1968","published-online":{"date-parts":[[2021,7,14]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"10Q902","DOI":"10.1063\/1.1849052","article-title":"Gd5(Si, Ge)4 and Gd2C compounds: Candidates for hyperthermia treatment of cancer","volume":"97","author":"Ahmad","year":"2005","journal-title":"J.
