**4. Foil ferrite as functional green device**

This section discusses the possibility of the functional green devices built by foil ferrite samples. Electrical performance under both longitudinal and transverse bias conditions has confirmed nonlinear behavior which obeys at the conduction properties through orderly small grained structure being it equivalent to the magnetic-electrical conduct of a self-inductor with hysteresis when it is connected as shown in **Figure 6**. Current-voltage (I-V) curves are obtained by using a digital storage oscilloscope (Tektronix, TDS1012C) at room temperature. A function generator (Matrix, MFG-8250A) was used to produce the input voltage signals.

To connect the input signal and collect the output signal in the applications shown here, two aluminum electrodes of circular geometry with cross section area of 0.1 × 0.1 cm2 have been placed on each foil ferrite; also, a resistor has been used to measuring of the output signals.
