Magnetic properties of the synthesized nanoparticles and films have been investigated. It was shown that the obtained nanoparticles exhibit superparamagnetic properties. It has been found that the synthesized nanoparticles have promise in hyperthermia of cancer cells. It has been shown that the films based on barium hexaferrite can have promise in the creation of nonlinear resonant microwave elements on the basis of high-Q dielectric resonators and ferromagnetic film.","PeriodicalId":142377,"journal":{"name":"International Conference on Oxide Materials for Electronic Engineering - fabrication, properties and applications (OMEE-2014)","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-05-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123752569","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
