Quantum Design MPMS XL-5 SQUID Magnetometer

mpms

Description:

The Quantum Design MPMS XL-5 SQUID Magnetometer is a very sensitive tool to measure the magnetization of materials, as function of temperature and magnetic field.

Specifications:
Features & Info sheet:
  • High sensitivity: MPMS sample magnetometers employ SQUID (Superconducting Quantum Interference Device) technology, to achieve superior measurement sensitivity and dynamic range.

  • Flexible operation: the MPMS incorporates all the hardware and software needed for precise magnetic measurements in a fully integrated, modular system.

  • DC Magnetization: this is the magnetic moment per unit volume (M) of a sample. If the sample doesn't have a permanent magnetic moment, a field is applied to induce one.

  • AC Susceptibility: values measured include real and imaginary susceptibility, which are used to determine frequency dependence and relaxation effects.

  • Automated measurements: Instruction files of up to 1500 steps can be created for immediate use, or stored on disk for later access.

Options:
  1. RSO - Reciprocal sample measurement

  2. AC susceptibility

  3. Low field

  4. Fiber optic sample holder

  5. External device control + transport probe

Restrictions:

The insrument requires liquid helium for operation, thus a very tight schedule of use is practiced when the dewar is cold. Extereme care is required with sample mounting.

Zeta Potential Measurement

photo09photo10

Description:

measurement of zeta potential is used to assess the charging level of small particles dispersed in a liquid. Such colloidal particles may be either macromolecules, or nanometric organic or inorganic particles. This potential reflects the inter-particle repulsion strength and thus provides a measure of the colloidal stability.

Specifications:

Particle size range: 5 nm – 10 µm
Minimal sample volume: 0.75 mL
Maximal sample conductivity: 200 mS/cm
Minimal concentration depends on refractive index of nanoparticles and size.

Measeurements:

The instrument is easy to operate. The disposable measurement cells contain the electrodes and thus contamination between samples is avoided. Each measurement should start with measuring a standard sample to verify proper operation of the instrument. It is important that the samples will be as uniform as possible, without contamination of large particles that would scatter light.

Physical Properties Measurement System

This system is an automatic cryogenic station with a temperature range of 2K-350K (He4 insert) or 0.35K-300K (He3 refrigerator). It is equipped with a superconducting magnet of 14 Tesla and a rotator probe (He4 only).
The following modules are available:

  1. DC resistance measurement
  2. Heat Capacity
  3. Vibration sample magnetometer

What should I do if I want to measure in this system?

  1. Define your measurement if it is a one shot experiment we will do it for you.
  2. If you need the system for a few measurements we will train you on the system, and you will need to buy your sample holder (which degrades with time)

A few FAQ’s

  1. Can I connect my external instruments? Yes, but you will need to write a short procedure in C++ so the instruments can communicate with the system. We are using Keithley delta mode Lock in amplifiers for precise resistivity and Hall measurements and Keithley DC amplifier to measure thermal transport and Nernst effect and we have a special probe for shining light on the samples at cryogenic temperatures and under vacuum.
  2. How long will I wait in line? The schedule is set two weeks in advance. Usually you will get 2 days within two weeks.
  3. How much will I pay? The Helium consumption is paid for separately ($5/ Litter, there is a He level meter in the machine, an overhead of 25% will be charged for He transfer and system cool down) In addition there is a charge of 4$ paid directly to the nanocenter (8$ if you do not have a nano-account)
  4. Where is the system? In the Physics basement, Kaploon building 0013 (internal room)
