Deposition and Characterization of FeB thin films by Electrochemical Method

Abstract

Magnetostrictive materials exhibit a resonant frequency under an alternating magnetic field. Amorphous iron-boron film is well known as a magnetostrictive material. In order to obtain an amorphous phase of FeB thin film by electrochemical deposition, solution deposition parameters -such as current density, solution concentration, and ratio of precursors -was investigated. The amorphous FeB thin films were deposited at higher current densities and concentration of the solution. The relationship between phase formation and kinetic effect was also studied. Magnetic behavior of these films was examined by measuring the resonant frequency.

High frequency magnetic properties of ferromagnetic thin films and magnetization dynamics of coherent precession

“…In ferromagnetic metal films, nanocrystallization with doping nonmagnetic elements, such as CoM (M = Zr, Hf, TaN), [104][105][106] FeM (M = B, Hf, Zr), [107][108][109][110] FeCoM (M = B, Hf, Zr), [111][112][113] are effective approaches to obtain IPUMA, which utilizes the dipole interaction between two phases with different magnetizations. [114,115] In addition, the magnetic anisotropy of a granular system with doping nonmagnetic oxide materials, such as SiO 2 , [116] TiO 2 , [117] Al 2 O 3 , [118] is controlled by changing the effective magnetocrystalline anisotropy of the magnetic nanoparticles.…”
