Extraordinary magnetization of amorphous TbDyFe films
Giant magnetostrictive, amorphous TbDyFe thin films prepared by magnetron sputtering. Presents giant magnetostriction of 300400ppm at room temperature. Spin-glass behavior at temperatures lower than 200K. Huge coercivity values were observed at T<40K reaching 2.5T at T=5K.
