In the last few years there has been increasing interest in CoP electrodeposited alloys due to their excellent properties as soft magnetic materials (low coercivity and high permeability) in addition to the giant magnetoimpedance that they exhibit. More recently magneto-impedance (MI) effect has also been reported on thin films obtained by sputtering techniques. Most of the studies performed on MI have been carried out on wires or ribbons, where the sensor shape was conditioned by its manufacturing process. However these limitations disappear on samples grown by sputtering or electrolysis where the geometry of sensors can be defined by using photolithographic techniques. In this work we have studied the giant magnetoimpedance in CoP films. The influence of the thickness of ferromagnetic material, conductive material, the frequency and intensity excitement and the geometric shape of the samples has been investigated.

Energetic Characterization

In recent years, innovative magnetic materials have been introduced in the field of electrical machines. In the ambit of soft magnetic materials, laminated steels guarantee good robustness and high magnetic performance but, in some high-frequency applications, can be replaced by Soft Magnetic Composite (SMC) materials. SMC materials allow us to reduce the eddy currents and to design innovative 3D magnetic circuits. In general, SMCs are characterized at room temperature, but as electrical machines operate at high temperature (around 100 °C), an investigation analysis of the temperature effect has been carried out on these materials; in particular, three SMC samples with different binder percentages and process parameters have been considered for magnetic and energetic characterization.
