The induced magnetic form factor of paramagnetic platinum was measured in an external field of 73 kOe at a temperature of 78 K. The data obtained for the six innermost Bragg reflections show that the spherically average magnetization density is in excellent agreement with that calculated by Watson-Yang. Freeman and Koelling. The result confirms the reliability of the present day band calculations, as well as assuring that the nontrivial orbital contribution to the form factor (g = 2.61) has been handled properly. The asphericity of the magnetization was more poorly determined, yielding at t2g population of 70 ± 17%, to be compared with a calculated value of 93%. An attempt at a more direct determination of the role of the orbital contribution is described.
