Voltage and temperature dependence of the grain boundary tunneling magnetoresistance in manganites

– We have performed a systematic analysis of the voltage and temperature dependence of the tunneling magnetoresistance (TMR) of grain boundaries (GB) in the manganites. We find a strong decrease of the TMR with increasing voltage and temperature. The decrease of the TMR with increasing voltage scales with an increase of the inelastic tunneling current due to multi-step inelastic tunneling via l...

Resistivity dependence of magnetoresistance in Co/ZnO films

We report the dependence of magnetoresistance effect on resistivity (ρ) in Co/ZnO films deposited by magnetron sputtering at different sputtering pressures with different ZnO contents. The magnitude of the resistivity reflects different carrier transport regimes ranging from metallic to hopping behaviors. Large room-temperature magnetoresistance greater than 8% is obtained in the resistivity ra...

Temperature dependence of magnetoresistance and Hall effect in Mg2NiHx films

The electrical resistivity, Hall effect, and magnetoresistance of Mg2NiHx (0,x,4) films are investigated as a function of temperature, between 2 K and 280 K and magnetic fields up to 7 T. The overall features exhibited by the electrical resistivity r and the charge-carrier density n at 4.2 K in Mg2NiH42d are those of a heavily doped semiconductor. As a function of x, accompanied by an increase ...

Texture Development Dependence on Grain Boundary Properties

The motivation for this work is to explain the development of special textures during recrystallization such as the cube component, {001}<100> in fcc metals. Monte Carlo simulation is used with two different mobility and energy functions. The energy function has little influence on texture development whereas the mobility function has a strong influence. A mobility function with a single broad ...

Misorientation Dependence of the Grain Boundary Energy in Magnesia

Geometric and crystallographic data obtained from a well annealed magnesia polycrystal have been used to specify the five macroscopic degrees of freedom for 4665 grain boundaries. The results indicate, that for this sample, the five parameter grain boundary character space is fully occupied. A finite series of symmetrized spherical harmonics has been used to approximate the misorientation depen...
