Opis:: Three different kinds of polymer films, poly (divinylbenzene), poly (ethylene glycol dimethacrylate) and poly (vinyl alcohol), containing M-type hexagonal barium ferrites (BaFe12O19) were synthesized on glass substrates by using surface polymerization method. The structural properties were characterized by X-ray diffraction and atomic force microscopy. X-ray diffraction patterns show that polymer films have a polycrystalline structure. The magnetic measurement of polymer films were examined at room temperature using vibrating sample magnetometer and magnetic force microscopy, respectively. The magnetic measurements indicate that P(VA)-BF films exhibit higher saturation magnetization and coercive field than P(EGDMA)-BF and P(DVB)-BF films.

Opis:: This paper studies embedded solitons that are confined to continuous spectrum, with $χ^{(2)}$ and $χ^{(3)}$ nonlinear susceptibilities. Bright and singular soliton solutions are obtained by the method of undetermined coefficients. Subsequently, the Lie symmetry analysis and mapping method retrieves additional solutions to the model such as shock waves, singular solitons, cnoidal waves, and several others. Finally, a conservation law for this model is secured through the Lie symmetry analysis.
