“…The value of specific loss power (SLP) was calculated on the basis of these results and it is 14.7 W/g. After comparing La 1x Sr x MnO 3 nanoparticles synthesized by precipitation from diethylene glycol solution with nanoparticles obtained by sol-gel method [15,27], it should be mentioned that there are no "bridge" bonds between individual particles, i.e., they are weakly agglomerated ( Fig. 6(2)).…”

“…Among well-known synthesis methods of nanoparticles of heterosubstituted lanthanum manganites, we can single out sol-gel method [15][16][17], co-precipitation from aqueous solutions [18], synthesis by precipitation from microemulsions [19], which allow obtaining nanoparticles in a wide range of size and property. However, each of the above-mentioned methods has drawbacks.…”

La 1x Sr x MnO 3 nanoparticles were synthesized by precipitation from diethylene glycol solution. Features of synthesis were studied using 1 Н, 13 С, 139 La nuclear magnetic resonance (NMR) investigations. The obtained results showed that the complexation reaction between diethylene glycol and metal cations takes place during the synthesis. These complexes decomposed at 200 ℃ and an amorphous precursor (La,Sr)MnO 3 was formed. According to X-ray results, the crystallization of the perovskite structure began at 600 ℃ and finished at 800 ℃. Microstructural studies showed that obtained nanoparticles are weakly agglomerated and have small sizes. Based on these nanoparticles, magnetic fluid was prepared which was effectively heated under an alternating magnetic field.

“…Особливістю цієї методи є те, що зразки одержуються при високій температурі (понад 1200С), а процес синтези перебігає з утворенням великої кількости проміжних фаз [15]. На відміну від твердофазної синтези, золь-ґель-метода ґрунтується на викорис-танні однорідної суміші реаґентів і уможливлює значно зменшити температуру одержання однофазного продукту з малим розміром і однорідним за розміром зерном [16].…”

Досліджено структурні, електричні та магнеторезистивні властивості зразків La 1x Sr x MnO 3 (х  0,15-0,60), виготовлених золь-ґель-методою. Кристалографічні параметри визначалися за допомогою рентґенівської дифракції. Вимірювання електричних властивостей виконувалися в тем-пературному інтервалі 77-380 К як у магнетному полі, так і без нього. Проаналізовано температурні залежності електричних та магнеторезис-тивних властивостей сполуки при різних концентраціях Sr. Встановлено концентраційну залежність температури Кюрі Т С для сполуки La 1x Sr x MnO 3 .
