An automatic spinner magnetometer with thermal demagnetization equipment

Abstract

We have developed a fully automated spinner magnetometer which can operate, under the control of a personal computer, the measurement of remanence as well as thermal demagnetization of paleomagnetic samples. This instrument is ideally suited for performing paleointensity experiments by the Thellier method because a series of measurements after heating cycles with or without an applied field can be programmed and carried out automatically by computer control. -from Authors
