More science, less time
VSMs have long been the benchmark for characterising magnet properties in material science laboratories.
The 8600 Series vibrating sample magnetometer raises the bar for magnetometer performance and convenience. These VSMs combine high sensitivity (15 nemu), rapid measurement speed (10 ms/pt), and simple operation for more accurate measurements, faster.
8600 Series Features
- 0.15 × 10-7 emu noise floor at 10 s/pt
- 10 ms/pt data acquisition rate
- 10,000 Oe/s field ramp rate
- Rapid, repeatable temperature option exchange
- High stability—±0.05% per day
- Fields to 3.26 T
- Widest available temperature range—4.2 K to 1273 K
- Includes fully automated FORC data acquisition software
The entire 8600 Series system has been reimagined with a focus on clean, ergonomic design that simplifies the researcher’s interaction with the system. A motorised head brings the sample to a comfortable height for easy, one-handed exchange of the QuickLIGN™ sample rods. Temperature options include a cryostat, high-temperature oven, and single stage variable temperature insert. The combined temperature range of the options is 4.2 K to 1273 K. All three GlideLOCK™ options quickly slide into place and are auto-detected, with the software automatically displaying controls for the specific option. The magnet poles are also easily adjusted with the ExactGAP™ indexed positioning system that allows the pole gap to be set at one of six repeatable positions, eliminating the need to recalibrate after each change.
Flexible and adaptable
The system’s software simplifies control of the VSM. Standard predefined measurement routines are combined with configurable field and measurement loops to provide a flexible data acquisition environment. In addition, the software features an integrated scripting tool, which enables the user to extend the existing routines with an open-ended software scripting language that can be used to perform customised measurement protocols and interface with third-party lab equipment.

Designed for FORC
The 8600 Series VSM offers the ultimate in measurement capability for researchers studying emerging low-moment magnetic materials, applying FORC analysis, or simply interested in making high-resolution measurements in less time.
The 8600 Series was created with first order reversal curve (FORC) measurement as a primary objective. FORC analysis precision is greatly enhanced by the high sensitivity of the 8600 Series. FORC also benefits from increased data point density, and the new VSM flies through complex FORC data collection sequences in a fraction of the time required on previous systems.
Lake Shore have recently taken FORC capability a step further with new Real-Time FORC (RTForc™) software, available for new and existing 8600 Series VSM customers as part of our 8600 V1.40 software release.
Enabling fully automated FORC data acquisition using the 8600 Series software, RTForc calculates and displays FORC distributions in real time, significantly reducing the time required by researchers to collect and analyse FORC data. In addition, users can change between the (Ha, Hb) and (Hc, Hu) coordinate systems, select smoothing factors (SF) and number of contours to be displayed, export the FORC diagram image, etc. Output data is compatible with FORCinel post-processing software.
Application Note: 8600 Series Vector Vibrating Sample Magnetometer (VSM) – download now
This application note, written by Lake Shore Senior Scientist and VP Brad Dodrill, describes a vibrating sample magnetometer with the vector option (VVSM), or biaxial VSM. In addition to standard hysteresis loop measurements, it provides for measurement of the angular dependence of the vector components of the total magnetisation, and also provides for indirect measurement of torque curves for anisotropy constant determinations.
The need to characterise new and emerging materials continues to push the limits of electromagnet-based VSM systems. The 8600 Series VSM steps up to meet the most demanding material research applications.
Extremely fast data acquisition cycles make the system ideal for research environments where rapid measurement results can accelerate the discovery of important new properties. QuickLIGN™ sample holders are offered for thin film, liquid, powder, and bulk samples, making the VSM an excellent choice for busy labs with varying sample measurement needs.
The high sensitivity of the 8600 Series VSM particularly benefits research into low moment materials such as ultra-thin magnetic films and multilayers, nanoscale magnetic materials, dilute magnetic semiconductors, and paleomagnets. Find out more
