Strongly correlated electron systems, especially the perovskite oxides with the general formula ABO3, have been studied for some decades due to their intriguing properties such as magnetism, mutiferroicity, ferroelectricity, colossal magnetoresistence and superconductivity [1]. In light of the previous studies of ABO3, A-site and B-site doping in these systems can lead to different crystal structures,...
We present a detailed analysis of substrate bias (Vbb) impact on gate induced drain leakage (GIDL) for thin-BOX extremely thin silicon-on-insulator (ETSOI) with BOX thickness (TBOX) ranging from 10 to 50 nm and inversion layer thicknesses (TINV) ranging from 1.1 to 1.3 nm. The GIDL behavior for thin-BOX under various substrate biases (Vbb) and partially depleted SOI (PDSOI) devices with different...
In this paper, we investigated the effect of diluted Gd doping on the magnetic properties of Fe50Co50 thin films by Vibrating Sample Magnetometer (VSM) and Ferromagnetic Resonance (FMR). The Gilbert damping coefficient corresponding to magnetization switching time was also determined.
In this research, the magnetic properties of Ni78Fe22 thin films by low doping of Tb additives are investigated. The composition of the films was determined by energy dispersive X-ray fluorescence spectrometer (EDS), and the structure of the films with different concentration of Tb was investigated by X-ray diffraction (XRD). The static magnetic properties were measured by Vibrating Sample magnetometer...
Ca3-xBaxCo4O9 (x = 0~0.4) bulks were prepared by sol-gel and spark plasma sintering (SPS) method, and the effects of preparation process on texture and thermoelectric properties were discussed in detail. The results show that SPS process is helpful to form texture. The bulks are composed of plate-like grains, which are aligned to (001) plane. To some extent, the orientation and density of Ca3Co4O9...
In this paper, the structure, magnetic properties and magnetic entropy change of Er2-xCexFe17 compounds have been studied. The results show that even crystal structure of the compounds is still the Th2Ni17-type hexagonal by Ce substituting for Er in Er2Fe17 compound, the exchange coupling coefficients have been changed between the Er and Fe sublattices, resulting in the Curie temperature of (Er,Ce)...
