Method for synthesis of magnetically sensitive nanostructures based on nanocrystalline magnetite containing gadolinium and boron is developed. Composition and structure of the synthesized compounds are studied by the atomic emission spectrometry with inductively coupled plasma, X-ray diffraction analysis, and X-ray photoelectron spectroscopy. As found, the synthesis on the surface of nanosized magnetite particles leads to formation an amorphous phase of gadolinium borate. The formation of GdBO$_{3}$ crystalline phase takes place after annealing at 950°C.

Key words: nanostructures, magnetite, boron, gadolinium, inorganic scintillators, boron-neutron capture therapy, neutron capture agent.
