Magnon Variable Field Susceptibility Meter VFSM

Linux software: N.R.Nowaczyk.

Analytical performance:

Measurement of magnetic susceptibility of discrete samples versus field and/or frequency. The original manual operation has been replaced by a simple (currently experimental) stepping motor controlled automation.

NOTE: The mains frequency (Germany: 50 Hz) and its multiples have to be avoided! Thus, useful frequencies are f = n*50+25 Hz.

Sensitivity:

100 µT400 µT
100 Hz : 10e-5100 Hz : 2x10e-6
1000 Hz : 10e-61000 Hz : 2x10e-7
10000 Hz : 10e-710000 Hz : 2x10e-8

Samples:

cubic or cylindrical samples with up to 10 ccm volume.

Application:

Rock magnetic investigations of terrestrial, lacustrine or marine sediment sequences, or hard rocks.
