✦ Synopsis

The conduction electron g-factor in Au was measured with three different techniques using the de Haas-van Alphen effect. On the neck orbits, the three techniques are in very good agreement and show a variation in the g-factor of ~60%, with a minimum of 1.15 at (111). On the belly at an isolated spin splitting zero at 71.6~

(100) the g-factor was found to be 2.35. A calibration procedure for the field modulation technique which allows accurate measurement of absolute amplitudes is presented. Absolute amplitudes measured with this procedure compare favorably with those made by torque magnetometer. A detailed discussion of magnetic interaction is given, including the effects of the vector nature of the magnetization and local demagnetizing fields caused by finite sample size.
