PMC MicroMag 3900 Series VSM

PMC MicroMag 3900

The PMC 3900 Series VSM has been discontinued. Please consider the 8600 Series VSM as a replacement.

Features of the 3900 Series

  • Very versatile — can also ordered as a dual-head VSM/AGM system or upgraded to a combination system later
  • High sensitivity (0.5 µemu standard deviation at 1 s/point)
  • Conduct experiments faster with signal averages as fast as 10 ms/pt
  • Versatile, quick-change sample holders for measuring solid, thin‑film, powder, and liquid samples
  • Continuous sample rotation about z-axis under computer control
  • High-speed four-quadrant magnet power supply
  • Easy-to-use Windows® based application software
  • Hardware and software compatible with 2900 Series AGM
  • High- and low-temperature accessories available

​The 3900 Series MicroMag™ system establishes a new standard of performance for vibrating sample magnetometers. High sensitivity (0.5 µemu at 1 s/point, 0.1 µemu at 10 s/point), high speed measurements (10 ms/point), a fast four-quadrant power supply, and either a 2 in or 4 in laboratory electromagnet plus comprehensive Windows®-based operating software make the 3900 Series a state-of-the-art magnetic measurement system.

Anisotropy measurements are facilitated by a driver head that provides continuous rotation about the z-axis (under computer control). Precision x, y, z translation stages permit fast and accurate sample placement. Sample holders accommodate a wide variety of thin films, solids, powders and liquids. A quick-release collet and reduced length drive rods allow rapid sample interchange.

The 3900 Series MicroMag™ system accommodates all types of samples (up to 5 × 5 × 5 mm): solids, ultra thin films, powders, liquids and even slurries. Applications include measurements of magnetic recording media, MRAM, GMR and TMR heads, amorphous metals, rare earth magnets, high temperature superconductors, nanomagnets, ferrofluids, biological specimens, toner material, magneto-optic devices, paleomagnetic samples and diamagnetic and paramagnetic materials.

Optional LHe or LN2 low temperature accessories and a high temperature furnace option are available for the VSM.

PMC MicroMag combination AGM/VSM system

Combination system also available—Major components of the VSM system, including system operating software, are fully compatible with the MicroMag™ 2900 Series AGM, permitting a combination of the techniques to serve an even greater range of applications. The integrated design of the combination VSM/AGM system is an economic way of having maximum measurement capability.
