Magnetic properties of Fe and Tb in Tb_xFe_1-x amorphous films studied with soft X-ray circular and linear dichroism

We have used linearly and circularly polarized X-rays to determine the magnetic properties of several TbxFe1-x amorphous films. Absorption measurements on the M4.5 edges of Tb and the L2.3 edges of Fe allowed us to obtain information about the size and direction of local magnetic moments. Our results confirm that linear dichorism in rare earth M4.5 edges can give useful information about both crystal field and magnetic effects. © 1995.
