Lake Shore 8600 Vibrating Sample Magnetometer (VSM)

Specifications:

• Temperature range: 100 K -- 1273 K
  • Single Stage Variable Temperature (SSVT) adapter (100 K -- 950 K). Liquid Nitrogen used for low-temperature measurements (stable from > 100 K). Argon and nitrogen gases are used during heating and cooling between room-temperature and 950 K. Preferred for measurements when continually varying temperature, e.g., Ms-T curves.
  • High temperature oven (303 K -- 1273 K). Measurements are made in argon gas. Preferred when holding a specific temperature steps, e.g., high-T hysteresis loops or FORC diagrams.
  • More details on the SSVT and Oven can be found on the Lake Shore Cryotronics website.
• Field range: 0 T -- 2.5 T (maximum field variable with pole gap)
  • For in-field measurements (hysteresis and FORCs) the maximum applied field is 1.8 T.
  • For remanence curves (IRM and backfield curves) a maximum saturation magnetization of 2.5 T can be applied.
• Sensitivity: 10E^-9 Am²
• Can accommodate rock chips, capsules in straws and thin film holders.
• Multiple holders available.
• Field gap can be adjusted.

Measurement Types:

Typically used for:

• Hysteresis loops.
• Backfield remanence curves.
• Isothermal Remanent Magnetization (IRM) acquisition curves.
• First Order Reversal Curves (FORC).
