HIGH-FIELD TRANSPORT PROPERTIES OF T'-Ln_2-xCe_xCuO₄ (Ln=Nd, Pr, La)

International Journal of Modern Physics B, 2002
We report low-temperature magnetotransport in the normal state of the electron-doped superconductors, Nd 2-x Ce x CuO 4, Pr 2-x Ce x CuO 4, and La 2-x Ce x CuO 4, by suppressing the superconductivity with high magnetic fields. The normal state ρ-T curve shows an up-turn at low temperatures, which has a log T dependence with saturation at lowest ...

SYNTHESIS OF Bi-Zn-Al-B-Si-O NANO-GLASS FOR MULTILAYER CHIP INDUCTORS

Modern Physics Letters B, 2009
The ferrite added with Bi - Zn - Al - B - Si - O nano-glass was sintered at 840-900°C, 2 h and the initial permeability, quality factor, density and saturation magnetization of the samples were measured. The initial permeability of the nano-glass added sample was about 62.6 at 0.1 wt%, and showed a sharp increase from 0.4 to 0.5 wt%.

STRUCTURE AND MAGNETIC PROPERTIES OF Co₁₂X(X = Ni, Ag, Pt, Au) CLUSTERS

International Journal of Modern Physics B, 2007
The ground state structures of Co 12 X ( X = Ni , Ag , Pt , Au ) clusters are obtained by a genetic algorithm with a Gupta-like many-body potential, and further optimized using the density functional theory with generalized gradient approximation. The structures of Co 12 X have a slightly distorted icosahedral pattern. The X atom is on the surface for

Electrical Comparison of Ta/Ti/Al/Mo/Au and Ti/Al/Mo/Au Ohmic Contacts on Undoped GaN HEMTs Structure with AlN Interlayer

Advanced Semiconductor Devices, 2007
A significant improvement of contact transfer resistance on undoped GaN/AlGaN/AlN (10 Å)/ GaN high electron mobility transistor (HEMT) structure was demonstrated using a Ta/Ti/Al/Mo/Au metallization scheme compared to a Ti/Al/Mo/Au metallization scheme.

Superconducting Properties of Bi-Sr-Ca-Cu-O Crystallized Glass

International Journal of Modern Physics B, 1999
This paper reports the crystallization and superconducting properties of Bi 4 Sr 3 Ca 3 Cu 4 O x glass-ceramics. The glass was prepared using the conventional melt-quenching method. X-ray diffraction pattern has shown that the annealing at temperature of 800°C converted the glass into glass-ceramics with Bi 2 Sr 2 CaCu 2 O x superconducting phase ...

THE FIRST PRINCIPLES CALCULATION OF STRUCTURAL, ELECTRONIC AND MAGNETIC PROPERTIES OF MnXY (X = Ru, Rh AND Y = Ga, Ge, Sb) ALLOYS

Modern Physics Letters B, 2011
The structural, electronic and magnetic properties of MnXY ( X = Ru , Rh and Y = Ga , Ge , Sb ) Heusler alloys are studied using density functional theory by the WIEN2k package. These materials are ferromagnetic. Also they have some interesting half-metallic properties.
