Quantum Design MPMS Magnetometer

Magnetic Property Measurement System

Quantum Design’s MPMS 3 provides users with the sensitivity of a SQUID (Superconducting Quantum Interference Device) magnetometer and the choice of multiple measurement modes, the MPMS 3 offers new levels of performance in magnetic research while including those aspects of past Quantum Design SQUID magnetometers that customers have grown to appreciate and depend on.

The MPMS 3 incorporates major advances in data acquisition, temperature control and magnetic field control with ≤10-8emu sensitivity. The award- winning design of Quantum Design’s MPMS 3 also provides expanded software functionality within its user-friendly MultiVu interface.

Technical Service and Application Support is available for the Quantum Design products – download the MPMS 3 service plan here

Combining the highest level of system performance with the possibility of using all previously available MPMS measurement options, the Quantum Design MPMS 3 truly represents the next generation of advanced SQUID magnetometry.

Options

ULTRA-LOW FIELD (ULF)

The ULF option uses a custom fluxgate field sensor in conjunction with in-situ concentric modulation and trim coils to actively cancel the residual magnetic field in the superconducting solenoid. The option also allows the experimenter to set fields up to +/- 25 Oe.

  • Field uniformity: +/- 0.05 Oe
  • Field nulling window: +/- 10 mm
  • Can be used in conjunction with any measurement mode or sample holder

FIBRE OPTIC SAMPLE HOLDER (FOSH)

The Fibre Optic Sample Holder (FOSH) enables light to be delivered to the sample space during a measurement.

  • Specialised sample rod and holder transmits a wide spectrum of light
  • Standardised fibre connection ensures compatibility with a variety of light sources
  • Compatible with traditional DC Scan, AC Susceptibility, ULF

LIGHT SOURCES

For experiments requiring illumination inside the MPMS 3 sample space, two broadband xenon light sources are available:

  • The TLX120Xe utilises a 100 W source and integrates a motorised monochromator such that the light wavelength can be selected using a sequence command in MultiVu
  • The MLS 300 W source includes a manual selection filter wheel for passing pre-determined wavelengths of light

AC RESISTANCE (ETO)

The Electrical Transport Option (ETO) enables AC resistance measurements of samples using a 4-probe lead configuration. For samples with higher resistances, a 2-probe high impedance mode is also available. Signals from two channels can be collected simultaneously. An additional voltage pass through allows for voltage-controlled magnetism studies.

  • Measure resistances of 10 μΩ – 10 MΩ in a standard 4-probe configuration
  • Resistances of 2 MΩ – 5 GΩ can be measured in the high-impedance 2-probe configuration
  • Automated I-V curve collection can be used to screen for ohmic contacts
  • Differential (dV/dI) resistance measurement mode
  • Compatible with traditional DC Scan, SQUID-VSM, AC Susceptibility (<10 Hz), ULF

PRESSURE CELL

The pressure cell option for magnetometry is manufactured by HMD, a leading Japanese supplier of pressure cells. A simplified design requires neither copper sealing rings or a hydraulic press to achieve the maximum available pressure of 1.3 GPa.

  • Included manometer materials: tin (Sn) and lead (Pb)
  • BeCu construction affords a minimal, uniform magnetic background
  • Compatible with traditional DC Scan, AC Susceptibility (<10 Hz), ULF

IR IMAGE FURNACE

2- and 4-Mirror Floating Zone Crystal Furnaces

The high-performance, compact IR Image Furnace from Quantum Design offers unsurpassed performance in a convenient, stand-alone design. Rivalling much larger and more costly IR furnaces, it uses the Floating Zone (FZ) method to promote single crystal growth from a polycrystalline rod. This method has been shown to be extremely effective for a wide class of materials. Now, more easily than ever before, you have the ability to synthesise superior quality single crystal specimens in your own laboratory.

TETRA ARC FURNACE

GES Corporation’s Tetra Arc Crystal Furnace uses the Czochralski pulling method and four electric arcs to grow a wide range of metallic-conductive materials such as metallic compounds and high-temperature superconductors. Achieving a 10-6 Torr vacuum within an hour, and using four electric arcs to heat materials up to 3000° C, this furnace provides easy operation and real time monitoring of the crystallisation process via CCD camera and four monitoring windows.

HELIUM-3 REFRIGERATOR

The iQuantum Helium-3 refrigerator extends the minimum temperature for DC and AC moment measurements below 0.5 K.

  • Continuous operation down to 0.5 K
  • < 3 hour cooldown time, 10 hours of 3He lifetime
  • Compatible with DC Scan and AC Susceptibility measurements

OVEN

The Oven option allows for magnetometry spanning temperatures of 300 – 1000 K. A special alumina sample holder with an integrated resistive heater and temperature sensor locally heat and sense the sample temperature.

  • User kit comes standard with high temperature Zircar cement and copper radiation shields for sample mounting
  • Moment Sensitivity 1·10-6 emu for H≤2500 Oe and 8·10-6 emu for H>2500 Oe
  • Compatible with traditional DC Scan, SQUID-VSM, AC Susceptibility (<10 Hz), ULF

HORIZONTAL ROTATOR

The Rotator enables the magnetometry as a function of angle, spanning a full 360°. A specially designed sample rod and stepper motor allow for automated integration into MultiVu. Three different rotor geometries allow for a variety of sample mounting possibilities to fully characterise anisotropic samples.

  • Range: up to 360°
  • Step Size: 0.1° (typical)
  • Compatible with traditional DC Scan, AC Susceptibility (<10 Hz), ULF

The AC Susceptibility option allows the experimenter to measure the dynamic (real and imaginary) response of a wide variety of samples including, but not limited to, superconductors, nanoparticles, and spin glasses.

  • AC Frequency Range: 0.1-1000 Hz
  • AC Field Amplitude: 0.1-10 Oe
  • Can be used in conjunction with any sample holder
