Evaluation of a long-time temperature drift in a commercial Quantum Design MPMS SQUID magnetometer using Gd2O3 as a standard
نویسندگان
چکیده
The long-time temperature drift in a commercial Quantum Design MPMS SQUID magnetometer was evaluated using time-dependent magnetization measurements of Gd2O3. In contrast to earlier claims, the amplitude of the drift was found not to exceed 1-1.5 K. 30 minutes after system stabilization the temperature deviation did not exceed 0.2 K and the temperature was fully stabilized in less than 3 hours.

Note: a sample holder design for sensitive magnetic measurements at high temperatures in a magnetic properties measurement system.
A sample holder design for high temperature measurements in a commercial MPMS SQUID magnetometer from Quantum Design is presented. It fulfills the requirements for the simultaneous use of the oven and reciprocating sample option (RSO) options, thus allowing sensitive magnetic measurements up to 800 K. Alternating current susceptibility can also be measured, since the holder does not induce any ...
متن کاملMeissner effect measurement of single indium particle using a customized on-chip nano-scale superconducting quantum interference device system
As many emergent phenomena of superconductivity appear on a smaller scale and at lower dimension, commercial magnetic property measurement systems (MPMSs) no longer provide the sensitivity necessary to study the Meissner effect of small superconductors. The nano-scale superconducting quantum interference device (nano-SQUID) is considered one of the most sensitive magnetic sensors for the magnet...

متن کاملA compact, high performance atomic magnetometer for biomedical applications.
We present a highly sensitive room-temperature atomic magnetometer (AM), designed for use in biomedical applications. The magnetometer sensor head is only 2 × 2 × 5 cm3 and is constructed using readily available, low-cost optical components. The magnetic field resolution of the AM is <10 fT Hz–1/2, which is comparable to cryogenically cooled superconducting quantum interference device (SQUID) m...
