Structural, Thermal, Optical, Electrical, and Adhesive Characteristics of FePdB Thin Films

Abstract EN

To study the structural, thermal, electrical, optical, and adhesive properties of magnetic FePdB thin films, 25–200-Å-thick Fe40Pd40B20 and Fe60Pd20B20 films were deposited on a glass substrate by direct current (DC) magnetron sputtering at room temperature (RT).

X-ray diffraction (XRD) patterns indicated that the 25–75-Å-thick Fe40Pd40B20 and Fe60Pd20B20 films were amorphous, whereas the 100–200-Å-thick Fe40Pd40B20 and Fe60Pd20B20 films were crystalline, with a face-centered cubic (FCC) FePd (111) textured structure.

The activation energy of the Fe40Pd40B20 and Fe60Pd20B20 thin films decreased as thickness was increased.

The 25-Å-thick Fe40Pd40B20 film exhibited the highest resistivity, whereas the 200-Å-thick Fe60Pd20B20 film exhibited the lowest resistivity.

Increasing the thickness and crystallization reduced transmission.

The Fe40Pd40B20 thin films exhibited higher surface energy and stronger adhesion than did Fe60Pd20B20 thin films.
