Phase diagram of LaCoO3-NdCoO3 system is built. As a result of investigations of luminescent properties of ceramic samples of YAlO3 : Mn, it is shown that the use of ordinary technology of solid phase synthesis in combination with annealing in an oxidizing atmosphere gives an opportunity to get to ceramic YAlO3 : Mn with high efficiency of thermoluminescence at a temperature higher than room temperature. Magnetic properties of the nanoparticles of iron oxide got by the method of cosedimentation of two- and thee- valent iron salts in an ammoniac environment and covered by the newest polymeric shell are investigated. The laboratory layout of device is created on that peculiarities of magnetic anisotropy of soft magnetic films in ferromodulation respond are studied under pendulum-like magnatisation reversal in the film plane by weak harmonic excitation field at presence of the permanent transversal displacement field.
