Abstract :
Ferromagnetic Resonance (FMR) study has been reported in β-phase p-NPNN (nitrophenyl nitronyl nitroxide) with Tc=0.6K. We have observed non-linear line shapes at the lowest temperatures. The line shape is related to the effect known as the “foldover effect” [1]. We confirmed that the temperature dependent g-value so far reported can be understood by the demagnetization effect using spherically shaped samples. An intrinsically anisotropic g-values are observed depending on the applied field directions. This is due to the anisotropy field along the crystal b-axis.
