Probably the most popular compound for the synthesis of complex hybrid structures especially during the last decade is a molecular silica matrix MCM-41. Many different classes of substances were obtained on its bases. Samarium is a well-known magnetic material and its salts are widely used in laboratories for research on new compounds of samarium. Therefore, we decided to insert the samarium-containing compound into MCM-41 matrix and investigate its electric properties from the perspective of magneto- and photosensitive applications. The samarium (III) chloride SmCl3 placed in mesoporous silica matrix MCM-41 with use of encapsulation technique was successfully synthesised. Electric properties of obtained nanohybrid encapsulate were investigated using impedance spectroscopy method. The character of impedance frequency dispersion, loss tangent and permittivity of MCM-41<SmCl3> synthesized material in darkness, under illumination and in magnetic field were determined. The thermogalvanic effect was observed and its mechanisms were analyzed. The observed magneto- and photoinduced negative capacitance effects for obtained МСМ-41 <SmCl3> nanohybrid opens up the possibilities for its application in nongyrator delay nanolines with optically and magnetically operable parameters.
