Abstract
A new MFK1-FA Kappabridge is introduced that precisely measures the magnetic susceptibility of rocks and the anisotropy of susceptibility. The instrument has the following features: separation of the in-phase (real) and out-of-phase (imaginary) components, auto-ranging and auto-zeroing, automated measurement of the field variation of the bulk susceptibility, AMS measurements using the spinning specimen method, built-in circuitry for controlling the non-magnetic furnace (CS-4) and cryostat (CS-L), full instrument control by an external computer, sophisticated hardware and software diagnostics. Examples are shown to illustrate the capability of the instrument for rock magnetic and palaeomagnetic research.
