Abstract
The dependence of perpendicular magnetic anisotropy on concentration and temperature in Fe100-x Nd x thin films (18 ≤x ≤60) fabricated by rf sputtering is described. The perpendicular magnetic anisotropy constant K u is maximum (\doteqdot1 ×107 erg/cc) for films with x=40 ∼45 made at substrate temperatures in the range from 220°C to 290°C. The presence of the maximum of K u as a function of temperature is also found for x= 35 and 40 at 40 K and 80 K, respectively.
