Superconducting Quantum Interference Device
About Instrument and its applications-
The Quantum Design MPMS XL SQUID uses a Superconducting Quantum Interference Device (SQUID) Magnetometer to monitor very small changes in magnetic flux and so discover the magnetic properties of samples. It is extremely sensitive for all kinds of AC and DC magnetic measurements. The SQUID detects and measures the Magnetic Moment of the sample. From this the magnetization and magnetic susceptibility can be determined.
Applications of the SQUID magnetometer include measurements of small quantities of paramagnetic ions, characterization of all kinds of magnetic materials, and quantitative determination of the number of unpaired electrons in samples. The MPMS-XL provides solutions for a unique class of sensitive magnetic measurements in key areas such as high-temperature superconductivity, biochemistry, and magnetic recording media. The modular MPMS design integrates a SQUID detection system, a precision temperature control unit residing in the bore of a high-field superconducting magnet, and a sophisticated computer operating system. Proprietary software, running within an intuitive MS Windows environment, allows full automation of all system parameters while controlling measurements, making data collection and analysis quick and easy.
MPMS Ever Cool
 The Quantum Design MPMS Ever Cool Dewar eliminates the need for liquid helium transfers and virtually all helium loss from the Quantum Design MPMS magnetometer system. The MPMS Ever Cool system features an integrated cryocooler-dewar system that recondenses the helium directly within the Ever Cool Dewar. Because the cold helium gas is recondensed at low temperature before it leaves the Dewar, the Ever Cool system is much more efficient in power consumption and cooling requirements than helium liquefying systems that recover the helium gas at room temperature
