The MicroMag™ Model 2900 (AGM) is a powerful system for measuring the magnetic properties of a vast range of materials. Extremely high sensitivity (10 nemu rms - corresponding to less than 50 pg of iron) and speed of measurement (100 ms per point), combined with compact design and ease of use, result in a system as well-suited to production test and quality control as it is to basic research.

The MicroMag™ system accommodates all types of samples (up to 5 x 5 x 2 mm: 200 mg mass): solids, ultra thin films, powders, liquids, and even slurries. Applications include measurements of magnetic recording media, MRAM, spin-valves, GMR heads, amorphous metals, rare earth compounds, high temperature superconductors, weak ferro fluids, biological specimens, toner material, magneto-optic devices, paleomagnetic samples and very weak diamagnetic and paramagnetic materials.

The extremely high measurement speeds of both MicroMag AGM and VSM systems are ideally suited to FIRST ORDER REVERSAL CURVE (F.O.R.C.) applications where large quantities of measurement data are required for post processing.

Included in the system are a modern Pentium® class personal computer, comprehensive Windows® based operating software and color printer. The MicroMag™ is available with a 2-inch or 4-inch laboratory electromagnet, each powered by a fast four-quadrant power supply, all under computer control. Optional LHe variable temperature cryostat with fully integrated temperature controller is available for low temperature studies.
