eng	Preparation of Manganese Perovskite Magnetic Nanoparticles and Their Mechanical Treatment	Magnetic nanoparticles of manganese perovskite La1-xSrxMnO3 (x = 0.25; 0.3; 0.35) could find applications as a contrast agent for magnetic resonance imaging or colloidal mediator for magnetic fluid hyperthermia. These nanoparticles have several times higher relaxivity and higher heating efficiency than the commercial products based on iron oxide. Nanoparticles of manganese perovskite were prepared by sol - gel method. Encapsulation by silica shell was performed using modified Stöber sol - gel method. Yield of encapsulated nanoparticles with suitable size is pretty small. A way how to eliminate this disadvantage is to find much more suitable mechanical treatment of raw magnetic cores. Magnetic cores after annealing are connected with “bridges” which have to be removed. Appropriate results were achieved by combination of rolling and milling rather than by milling only.
