Study of Magnetic Nanocomposites by NMR and Bulk Magnetization Techniques

Abstract

Magnetic nanocomposites possess complex and nonuniform magnetic structure. As a result it is necessary to use different physical methods to describe their properties. In this work we have applied a combination of micro and macro approaches to understand more deeply magnetic properties of some cobaltcontaining nanocomposites. Testing of magnetic structure of the samples at molecular level was done with NMR and Mössbauer techniques whereas static (SQUID) and dynamic magnetic (M2, see below) measurements – at macro level.
