摘要

采用溶胶-凝胶法、乙二醇溶液沉淀法和微乳液法制备了具有尖晶石和钙钛矿结构的La1-xSrxMnO3铁磁化合物，制备了微团聚的纳米颗粒。“核/壳”La1-xSrxMnO3/SiO2结构已被开发。研究了合成的纳米颗粒的磁性能。结果表明，制备的纳米颗粒具有超顺磁性。研究发现，合成的纳米颗粒在肿瘤细胞热疗方面具有广阔的应用前景。

Nanoparticles of ferromagnetic materials and possibilities of their application in the hyperthermia of malignant tumors

Slightly agglomerated, crystalline nanoparticles of ferromagnetic compounds with spinel and perovskite La_1-xSr_xMnO₃ structure have been synthesized by the sol-gel method, precipitation from glycol solutions and using microemulsion technique. “Core/shell” La_1-xSr_xMnO₃/SiO₂ structure have been developed. Magnetic properties of the synthesized nanoparticles 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.
