New Generation Magnetic Measurement System - MPMS3
In March 2013, Quantum Design announced the newly designed magnetic measurement system MPMS3 at the annual meeting of the American Physical Society. The system is still based on SQUID detection technology, but it is not a simple upgrade to the MPMS (SQUID) XL series and SQUID-VSM system. The MPMS3 system is the culmination of years of dedicated development by Quantum Design, which integrates a large number of new technologies.
Compared to MPMS XL and SQUID-VSM magnetic measurement systems, MPMS3 integrates the advantages of both. Although the appearance of the MPMS3 system is similar to that of SQUID-VSM, the system has been redesigned and has the high-speed and high-precision measurement capabilities of SQUID-VSM, as well as the DC measurement mode, Raw Data function, and Point to Point measurement function of MPMS XL. The system comes with new DC Scan measurement mode, VSM measurement mode, and AC measurement mode for users to choose from, which greatly meets their measurement requirements. MPMS3 is also very easy for MPMS XL users and SQUID-VSM users to get started with. In addition, for SQUID-VSM users, we also provide an upgrade plan, where users can upgrade their SQUID-VSM system to MPMS3 system.
The MPMS3 system comes with a new completely liquid helium free Evercool option, which can achieve full helium start-up and operation, completely eliminating dependence on liquid helium.
Application field:
MPMS is widely distributed in almost all relevant cutting-edge laboratories around the world and has a good reputation in the academic community. The MPMS system consists of a base system and various extension function options. The base system provides both a variable magnetic field measurement environment and a variable temperature field measurement environment. The extended function options include various fully automatic magnetic measurement function options, such as the AC magnetization measurement system option (for AC magnetization measurement, frequency 0.1Hz -1kHz, magnetic moment sensitivity ≤ 5 × 10-8 emu (typical)), high-temperature furnace option (to extend the instrument's high measurable temperature to 1000K), ultra-low magnetic field option, and magnetic field reset option (for demagnetization, ultra-low magnetic field up to 0.005G can be obtained). MPMS is equipped with a liquid helium self circulation system, which can fully automate the circulation and utilization of liquid helium, greatly facilitating users in regions where it is difficult to obtain liquid helium or where liquid helium prices are expensive.
The fields covered include physics, materials, chemistry, biology, geology, and other disciplines. The materials that can be studied and measured include metals, ceramics, semiconductors, superconductors, magnetic materials, alloy materials, organic materials, dielectric materials, and polymer materials. The forms of materials can be: bulk materials, thin films, powders, liquids, single crystals, and nanomaterials.
