Fe3o4 Thin Film

Polycrystalline magnetite (Fe3O4) thin films is synthesized at low temperature (90 oC) by electroless plating in aqueous solution, and the behavior of the magnetic property of the Fe3O4 thin film irradiated by Kr26+ ions at energy of 2.03 GeV is investigated by magnetization measurements. The initial crystallographic structure of the Fe3O4 remains unaffected after swift heavy ion (SHI) irradiation, but both coercive force and saturation magnetization are sensitive to Kr26+ ion irradiation and exhibit different behaviors depending on the ion fluence range. And SHI irradiation could make the magnetic moments of the Fe3O4 films ordered around the columnar defects and the magnetic moments tend to arrange along the films plane. All modifications of the magnetic properties could be interpreted very well by the effects related to the stress and defects induced by SHI irradiation.

Abstract Repercussion of Swift Heavy Ion (SHI) irradiation on nickel-based nanorods of Metal-Organic Framework (NRs-Ni3HHTP2-MOF) for enhancement in the properties of ChemFET based gas sensor has been investigated. Nanorods of Ni3HHTP2-MOF were synthesized by chemical method and exposed to C12+ ions irradiation with fluence 1x1011 ion/cm2 and 1x1012 ion/cm2. The structural, spectroscopic morphological and optical characterizations were carried out using x-ray diffraction (XRD), fourier transfer infrared spectroscopy (FTIR), atomic force microscopy (AFM) with scanning electron microscopy (SEM) and UV-visible spectroscopy were studied respectively. Whereas the bandgap was calculated from Tauc's plot. The synthesized nanorods of Ni3HHTP2 MOF were drop-casted on gold coated microelectrodes on silicon/silicon dioxide (Si/SiO2) substrate, where silicon layer serves as a gate and gold microelectrodes on silicon/silicon dioxide (Si/SiO2) substrate as a source and drain. The transmutations in material properties due to SHI irradiations were serviceable for enhancing field-effect transistor (transfer and output) properties.

Shi Irradiation

MnZn ferrite thin films are deposited by alternative sputtering technique from two targets with the composition of MnFe2O4 and ZnFe2O4, and the behavior of the magnetic properties of the MnZn ferrite thin films irradiated by Kr26+ ions at energy of 2.03 GeV is investigated by magnetization measurements. The fabricating and modifying conditions on the performance of the films are studied to improve Ms and reduce Hc of the films, making the films suitable to the applications of high-frequency film devices. For Mn1-xZnxFe2O4 thin films, the Ms increases firstly then decreases and Hc decreases monotonously with increasing Zn content. And both Ms and Hc are sensitive to Kr26+ ion irradiation and exhibit different behaviors depending on the ion fluence range. The modifications of the magnetic properties could be interpreted very well by the effects related to the stress and defects induced by SHI irradiation.
