In this study, antimony substituted yttrium iron garnet with a composition of (x = 0, 0.1, 0.2) nanoparticles were fabricated by Sol-Gel method. Garnet phase formation were investigated by X-Ray diffraction (XRD) and Fourier transform infrared spectroscopy (Far FT-IR). X-ray diffraction results show that the samples in addition to garnet phase has impurity phases of YIP, α-Fe2O3 and Sb2O4 whi...
Single-phase phosphors that emit broadband white-light are needed for white-light-emitting diodes (wLEDs) to reach their full potential. However, it is challenging achieve broad emission from single-phase materials. Consequently, polycrystalline inorganic bulk compounds sans doping rare. We report on a well-known garnet compound, i.e., yttrium iron (YIG), without activator-ion doping. Upon near...
We report strong damping enhancement in yttrium iron garnet (YIG) film due to spin inhomogeneity at the interface. The growth-induced thin interfacial gadolinium (GdIG) layer antiferromagnetically (AFM) exchange couples with top YIG layer. out-of-plane angular variation of ferromagnetic resonance linewidth $\mathrm{\ensuremath{\Delta}}H$ reflects a large inhomogeneous distribution effective mag...
Praseodymium ion (Pr3+) substituted yttrium iron garnet nanoparticles PrxY3-xFe5O12 (x = 0.0, 0.1, 0.2, 0.3, 0.4) were fabricated by the sol-gel method. X-ray diffraction (XRD) patterns confirmed the pure garnet structure for all samples. The chemical bonds and the garnet phase were studied by using Far-FTIR. The magnetic hyperfine parameters were obtained by MÖssbauer spectroscopy and confirme...
In this study, cerium substituted yttrium iron garnet thin films with nominal formulaY3-xCexFe5O12 and different x value (x = 0,0.1,0.3,0.5,0.7) were fabricated on quartz substrates viasol-gel method and spin coating technique. Samples taken to check physical characteristics. The effect of Ce doping on the structural properties , surface morphology and magnetization of the films were studied r...
