- Abstract
- Static and dynamic magnetostrictive behaviors of the TbFe/Ni/TbFe film are compared with a tri-layered TbFe film to discover the effects of a Ni thin layer on the improvement of magnetic moment and magnetostriction, as well as the reduction of dynamic response time under a low magnetic field. The Heisenberg model and Landau-Lifshitz-Gilbert equation were used to simulate magnetic domain motion. Time consumptions, in particular, were calculated to determine a uniformly magnetized state in Ni and TbFe layers. In addition, the magnetic moment together with the magnetostriction was examined with a fabricated magnetostrictive actuator. Contrary to a tri-layered conventional TbFe film, the TbFe/Ni/TbFe showed a higher magnetostrictive behavior even though a lower magnetic field was applied, corresponding to a low coercive force within the range of 0-10 kA/m. The dynamic magnetostriction response time, in particular, was also reduced to about 27 ms compared to the tri-layered TbFe film. (C) 2014 Elsevier B.V. All rights reserved.
