Designing spintronics materials with high Tc is a big challenge in the modern nanomaterialsĺ research. V[TCNE]\(_x\) is considered to be an excellent candidate for spintronics applications with some advanced properties. Ferrimagnetic resonance (FMR) of three high-Tc organic-based magnetic V[TCNE]\(_x\) films is reported. These samples prepared by chemical vapour deposition (CVD) method under different preparatory conditions have different transition temperatures: >300°K (sample A), 280°K (sample B), and 220°K (sample C). Their different magnetic parameters such as effective magnetization, full width at half maximum, etc. have being studied in the temperature range 10ľ300 K. Sample A shows long-range ordered magnetic behaviour, while samples B and C exhibit spin-glass-like behaviour.

Keywords: ferrimagnetics, spintronics, EPR spectroscopy, magnetization dynamics, surface magnetic properties
