MAGNETIC PROPERTIES OF RARE EARTH-IRON ALLOYS.
Abstract
The first objective of this study was to build and calibrate an apparatus for measuring magnetic properties of small ferromagnetic rod samples. The second was to measure the magnetic properties of five rare earth-iron alloys. Magnetic properties of neodymium-iron, praseodymium iron, and cerium-iron alloys were measured on small rod samples. Constant temperature plots of magnetization versus field (up to 24 kOe) as well as constant field plots of magnetization versus temperature (4.2K to 375K) were obtained for the samples. The apparatus provided an accurate and rapid means of obtaining magnetic data. The magnetization value obtained for a pure nickel sample was within .5% of published data. The 24 kOe field was not sufficient to reach the saturation magnetization of the rare earth alloys. The values of Curie temperature could not be obtained by extrapolating the spontaneous magnetization curve to the temperature axis.
