  • Magnetoelectronics is mainly digital, i.e. governed by up and down magnetizations. In contrast, analogue magnetoelectronics makes use of phenomena occuring for non-collinear magnetization configurations. Here we review theories which have recently been applied to the transport in non-collinear magnetic nanostructures in two and multiterminal structures, viz. random matrix and circuit theory. Both are not valid for highly transparent systems in a resistive environment like perpendicular metallic spin valves. The solution to this problem is a renormalization of the conventional and spin-mixing conductance parameters.

Architects use angles all the time in their daily work; they use them to measure ninety degree angles in making a wall. They are used in obtuse angles when making plane wings and acute angles are used to align the propellers the same distance apart. They use a 180 degree angles in making the body perfectly straight and proportional. Angles range from right angles to obtuse with sizes varying. Obtuse angles are more than 90 degrees and less than 180 degrees. Right angles are a perfect 90 degrees, acute angles are less than 90 degrees, and straight angles are 180 degrees.
