MPMS-3 (LOT-Quantum Design company) represents the culmination of development and design in the world of SQUID Magnetometry. Providing 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.
The MPMS 3 incorporates major advances in data acquisition, temperature (1.8 K ≤ T ≤ 400 K) control and magnetic field (-7T ≤ H ≤ +7 T) control with ≤10-8 emu sensitivity. The award-winning design of Quantum Design's MPMS 3 also provides expanded software functionality within its user-friendly MultiVu interface. 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.
MPMS 3 provides three possible measurement modes:
DC Scan Mode: Provides continual plotting and capture of raw data points at various fields and temperatures.
VSM Mode: Combines DC SQUID sensor with Vibrating Sample Magnetometer (VSM) technology, providing the ability to achieve < 10-8 emu sensitivity at zero magnetic field and <8*10-8 emu sensitivity at the full field of 7 tesla.
AC Susceptibility Mode: Using an oscillating magnetic field, this measurement uses the MPMS 3's SQUID and VSM linear motor to measure the AC Susceptibility of a sample.

The EverCool Dewar eliminates the need for liquid helium transfers and virtually eliminates all helium loss from magnetometer system. For the user, this integrated pulse-tube cryocooler dewar system can be considered cryogen free, as it not only recondenses the liquid helium directly within the EverCool Dewar but also accomplishes its initial cool-down directly from helium gas, thereby eliminating the need to use any liquid cryogens for the operation of the MPMS 3.

The Magneto-Optic Measurement option is a tool for investigations of photo-induced magnetization and related phenomena in samples. This option allows a sample to be illuminated by an external light source while conducting magnetic measurements. This option includes all the necessary parts and components to generate light of a certain wavelength and couple it in a Fiber Optic Sample Holder (FOSH) specifically designed for the MPMS3.

The Manual Insertion Utility Probe (MIUP) is a multifunction sample mounting platform, which is easily integrated into the base MPMS3. A micro-connector at the top of the sample rod connects 5 phosphor bronze wires to the sample mounting location. These 5 wires can be attached to the sample at the user’s discretion. The MIUP may be used for any application that necessitates up to 5 leads. Its design also allows users to perform a variety of resistivity measurements within the automated field and temperature environment that the MPMS 3 provides.
