Room Temperature Magnetic Response of Sputter Deposited TbDyFe Films as a Function of the Deposition Parameters
Source abstract
Abstract
Magnetostrictive thin films of the ternary compound (TbyDy1-y)x_{}Fe1-x have been prepared by magnetron sputtering from a Terfenol D target onto both room-temperature and high-temperature substrates (TS<550 °C). The aim is to select the deposition parameters of this highly magnetostrictive material in order to optimize its magnetic response. Films prepared on room-temperature substrates were amorphous and those deposited at high temperatures have a microstructure consisting of small grains of RFe2 compound and some RE oxide phases. Deposition temperatures around 550 °C promotes in-plane orientation of (220) and (311) planes of RFe2 phase. The magnetization measurements performed at room temperature showed that depending on the processing conditions the material changes from a soft magnetic behavior with perpendicular anisotropy to a two phase system with both hard and soft magnetic phases.
