Abstract
The ferromagnetic properties of thin films of nickel in the thickness range 20 Å to 495 Å are reported as a function of temperature between 4° K and 475° K. The behavior of the hysteresis loops is consistent with Kittel's theory. The data on saturation magnetization as a function of temperature is as yet not able to settle the question of the slope at T = 0, although better data is anticipated soon. The theory of Klein and Smith fits the observations of Curie temperature as a function of thickness surprisingly well.
