The search for the materials useful for spin-based electronics (spintronics) has been a very important part in the developing of spintronics technology and spin-based electronic devices. Organic-based semiconductor ferromagnets are a class of materials which have unique combination of properties suitable for sources or analyzers of spin-polarized currents are being studied by using different techniques as candidates for spintronics applications. Spintronics devices are starting to impact high-technology industries and could create new multibillion dollar industries which we could not always predict.
Ferromagnetic Resonance (FMR) technique along with other experimental methods are used to study a number of ferromagnetic semiconductors to get information about their chemical and crystal structure, surface and bulk properties, main parameters related to the conductivity and spins of the electrons.
This dissertation investigates temperature- and structure-dependent behavior of different generations of magnets V[TCNE]x and VxCo1-x[TCNE]2 (TCNE is tetracyano-ethylene). The obtained data have been analyzed using famous models for FMR in semi-conductors.
