Galvanomagnetic

In the frame of the itinerant model, the surface is represented by a potential barrier of various origins and shapes, in most cases treated as onedimensional problem (e.g., 56-60), without taking into account the potential variation in the plane of the surface3 [with the exception of (61) where this effect is qualitatively discussed in connection with the field ionization probability]. Obviously, the nonlocalized model is suitable and often used for the theoretical interpretation of the changes of the bulk properties of the metals caused by the surface effects (the changes of the electrical resistance, magnetic properties, galvanomagnetic effects, etc.).

The galvanomagnetic properties of nanocomposites and their conductivity, in particular, near the percolation transition can be described within the two-component model developed for the case by Efros and Shklovskii [73] on the basis of Dykhne theory [74]. This theory was developed just for the description of materials containing two different components with sharp distinction for conductivity values (Dykhne media) and describes well the concentration dependence of the effective conductivity in the case of the classical grain sizes and so in the absence of quantum effects. However, even if quantum effects do not play an essential role, the adequate description of the conductivity dependence on temperature has not been elaborated till now. The reason is that numerous experimental results for granules, with the metal contents x[Pg.612]

An effect of external factors on giant magnetoresistance (GMR) for asymmetric layer structure metal/polymer/non-magnetic metal was investigated. The magnetostriction, galvanomagnetic effects and instability of contacts are not the reasons for GMR appearance. The conclusion on the injective nature of the GMR effect was drawn. 

Galvanomagnetic effects and instability of contacts as the reasons for GMR indication were excluded by the great number of measurements under variable conditions. Since the polymer used is quite sensitive to mechanical pressure [4], it is important to study the influence of mechanical factors in magnetic field. The most important factor is the magnetostriction of nickel, because other artefacts can be destroyed by careful experimental performance. 

Bi nanowires have been grown from direct vapor into AM templates with diameters in the range 7 to 200 nm and their galvanomagnetic properties were studied [21]. The grown wires were single crystals. The method of growth is rather simple, the membrane is placed at the mouth of a crucible, which is kept in vacuum and contains molten Bi.
