ALERT

In observance of US Thanksgiving holiday, Agilent Cross Lab iLab Operations Software will be closed during US hours on Thursday November 23rd and Friday November 24th, 2017. EU and APAC support coverage will remain open during this time. We will resume US support hours on Monday November 27th, 2017. For urgent matters, please add "URGENT" to the ticket subject and these requests will be prioritized first.

Magnetic Characterization Facility

Overview of Services

The Magnetic Characterization Facility is designed to investigate a variety of key properties of materials, such as magnetic, electrical, thermal, and dielectric susceptibility at variable temperatures (2K-400K) and in high magnetic fields (up to 9 Tesla) and high pressure (12 GPa). The instruments can accommodate samples practically of any shape or form, from single crystals to bulk solids and powders and can be used for analysis of magnetic susceptibility, paramagnetic resonance, and other properties of complex newly synthesized compounds, nanoparticles, bio-magnetism, magnetic drug delivery, and therapeutic compounds. All the instruments are connected to the in-house liquefaction system, providing liquid helium for around the clock operation.

Available Equipment and Infrastructure

Quantum Design Magnetic Property System (MPMS) 

A Superconducting QUantum Interference Device (SQUID) magnetometer is an instrument for detecting and measuring extremely small magnetic fields. Quantum Design's MPMS incorporates data acquisition, temperature control (2K-400K) and magnetic field control (0-7T), providing users with better than 10-7 emu sensitivity of magnetic properties of materials (equivalent of several nanograms of iron, for example). A high pressure cell (up to 12 GPa) will soon become available.

 

 

 

Physical Property Measurement System (PPMS®) Options

  • Heat Capacity Option
  • AC Resistivity ρ
    • Measured by using precision current source and phase-sensitive voltage detection
  • Thermal Conductivity κ
    • Measured by applying heat from the heater shoe in order to create a user-specified temperature differential between the two thermometer shoes.
  • Seebeck Coefficient α; Thermoelectric Figure of Merit ZT
    • Measured by creating a specified temperature drop between the two thermometer shoes.
    • Determined here simply as the algebraic combination α2T /(κρ) of the three measured quantities - thermal conductivity, Seebeck coefficient, and AC electrical resistivity.
  • AC Susceptibility Option (ACMS II)
    • AC Susceptibility: Sensitivity: 1 x 10-8 emu; Amplitude: 0.005 Oe – 15 Oe (peak); Frequency Range: 10 Hz – 10 KHz; DC Magnetization; Sensitivity: 5 x 10-6 emu
  • AC Transport Option
    • AC Resistivity, Hall Effect, I-V Curve Tracing, and Critical Current measurements
    • 1 nV sensitivity, nΩ resolution at 2 A; Drive amplitude 10 μA to 2 A
  • DC Resistivity Option
    • Four independent channels for performing DC resistivity
