The methods of synthesis, properties investigation and ways of application of nanohybrid materials became a popular topic of a scientific interest during last decade. Mesoporous silica is a wide used material in the field because of its matrix structure for nanomaterial synthesis, biocompatibility and nontoxic properties. 
This work deals with synthesis by a encapsulation method [1, 2] and electric properties investigation of SmCl3 encapsulated in mesoporous silica matrix MCM-41 with use of impedance spectroscopy method. 
The character of impedance frequency dispersion, loss tangent and permittivity of <SmCl3>MCM-41 synthesised material in darkness, under illumination and in magnetic field was determined. The thermogalvanic effect was observed and its mechanisms were analysed.
