Decreasing of structural material-composing formations leads to the most significant change of magnetic properties of materials to nanosizes. This type of materials is different from the other types due to the several reasons. In the first place, the nature of observed changes of properties during the grinding of the product-forming particles was defined for this type of materials in the last century. In the second place, during the transfer to nanosize formations, the properties of these materials are significantly changed. Change of structural formations in magnetic materials is followed by certain phenomena: change of exchange interaction of electrons and material magnetization mechanisms with the change of coercive force; appearance of various states of material (ferromagnetic, paramagnetic and anti-ferromagnetic). Researches for the purposeful control of magnetic properties of materials and use of these results for manufacturing of various functionality products is of a great scientific and practical interest. This article shows the results of researches of the basic magnetic and mechanical properties of fabric magnetic materials, containing various phasesfillers on the basis of strontium ferrite particles. There was carried out the comparison of fabric magnetic materials on aramid and cotton base by the size of coercive force, residual magnetic induction, elasticity coefficient, fracture stress, tensile extension and a range of other characteristics, reflecting the parameters of researched materials.\

This article was prepared within the Agreement between the National University of Science and Technology “MISiS” and All-Russian Research Institute of Chemical Technologies (No. 1/2012 of November 20, 2012), realized with the financial support according to the Decree of the Government of Russian Federation of April 09, 2010 (No.218) «About the measures of the State support of development of cooperation of Russian universities and organizations, realizing the complex projects on the creation of high-technological production».
