MicroMag AGM/VSM 2900/3900 (Alternating Gradient Magnetometer/Vibrating Sample Magnetometer) This device is commonly used to determine the domain state (magnetic grain size) of ferromagnetic minerals through high resolution hysteresis measurements, isothermal remanent magnetization curves, FORC diagrams and non-linear Preisach maps.
MFK1-A kappabridge with CS3 furnance, CS-L cryostat and 3D rotator
The world’s most sensitive commercially available laboratory instruments, it is used to determine magnetic mineralogy and concentration of ferromagnetic minerals through measurements of anisotropy of magnetic susceptibility (AMS), magnetic susceptibility in variable magnetic fields, frequency dependence of magnetic susceptibility using 3 frequencies, temperature variation of magnetic susceptibility between -193C and 700C.
Thermal and alternating field up to 200 mT demagnetizers
These devices are usually used for determination of direction and intensity of Earth magnetic field in the past (from 1000 to several hundred thousand years ago) using alternating field (AF) and thermal demagnetization of rock samples. In addition both thermal and AF demagnetization allows identification of hard magnetic minerals in mixed magnetic mineralogy (for example magnetite + hematite).
SM100 + SM105 magnetic susceptibility meters
This device can measure is used to determine the real magnetic grain size distribution of ultrafine ferromagnetic minerals (< 20nm) by measuring the magnetic susceptibility in 14 different frequencies spanning four order of magnitude: 65 Hz, 125 Hz, 250 Hz, 500 Hz, 1000 Hz, 2000 Hz, 4000 Hz, 8000 Hz, 16000 Hz, 32 kHz, 64 kHz, 128 kHz, 256 kHz, 512 kHz
Magnetic Measurements 9 Tesla Pulse Magnetizer
This instrument is used for for creating Isothermal Remnant Magnetizations (IRM’s) up to 9 T pulsed fields allowing the detection of antiferromagnetic minerals presence like hematite and goethite in a sample dominated by soft magnetic minerals (usually magnetite and/or maghemite).
