Title: Study of magnetic properties and relaxation in amorphous Fe{sub 73.9}Nb{sub 3.1}Cu{sub 0.9}Si{sub 13.2}B{sub 8.9} thin films produced by ion beam sputtering

Abstract

Amorphous Fe{sub 73.9}Nb{sub 3.1}Cu{sub 0.9}Si{sub 13.2}B{sub 8.9} thin films have been produced by ion beam sputtering with two different beam energies (500 and 1000 eV). Magnetic measurements indicate that the samples display a uniaxial magnetic anisotropy, especially for samples prepared with the lower beam energy. Magnetization relaxation has been measured on both films with an alternating gradient force magnetometer and magneto-optical Kerr effect. Magnetization relaxation occurs on time scales of tens of seconds and can be described with a single stretched exponential function. Relaxation intensity turns out to be higher when measured along the easy magnetization axis.
