Abstract |
To form the sensing elements of the magnetic field sensors based on
magneto-resistance effect, it was suggested to use a method of layer
condensation in vacuum Co and Cu with the thickness of individual layers
from 1 to 20 nm and sequence depending on the functionality of the finished
sensitive element. For high-speed digital sensors, it is reasonable to form
multilayer nanostructures of a spin-valve “sandwich” type
Co(4÷12nm)/Cu(4÷8 nm)/Co(20 nm)/S (S - substrate). Co magneto-rough
lower layer is additionally secured by high temperature of substrate TS = 950 K
which provides high values of lower layer coercitivity Co. The sensor element
based on such a multilayer structure depending on the applied external
magnetic field can be located in two states “high” and “low” value of
resistance that can provide a stable state of logic “zero” and “unity.” |
