Quantum Design MPMS (SQUID-VSM Magnetometer)

The SQUID-VSM enables the characterisation of magnetisation as a function of applied magnetic field and temperature. Common uses of this equipment include field sweeps and hysteresis loops, magnetic moment vs. field and magnetic moment vs. temperature in field and zero-field measurements.

Specifications:

Magnetic Field

• Range: -7 to +7 T
• Field uniformity over 4cm: 0.01%
• Field changing rate: 4 to 700 Oe/second
• Field changing resolution: 0.33 Oe
• Remanent Field: 5 Oe (when oscillated from full field back to zero)
• Both in plane (quartz holder) and out-of-plane (straw) field measurements

Temperature (with normal cryostat)

• Range: 1.9 to 400 K
• Cooling rate:
  • From 300 to 10K: 15 minutes
  • From 10K to 1.9K: 5 minutes
• Temperature Stability +/-0.5%
• Temperature Accuracy: Either +/-1% or 0.5 K whichever is the smaller

Measurement of Magnetic Moments

• Maximum DC moment: 10 emu
• Sensitivity < 1x10^-8 emu

Sample Space

• Diameter of chamber: 9 mm
• Maximum sample size of 9 mm length by 5-6 mm diameter (sample to fit in a standard sized plastic drinking straw)

Options

• VSM AC measurements for magnetic susceptibility
• Additional accessory to apply electric current and voltage
