Can anyone help me explain the difference between VSM and Squid?
VSM is the abbreviation of the magnetic strength of the vibration sample. The VSM generally said that the vsm is a vibration sample magnetic force meter equipped with ordinary electromagnets, and Squid uses superconducting electromagnets to measure large electromagnetic fields. VSM is just a Squid one of the SquidSelected options, other options on Squid, such as TTO (thermal power), AC magnetization rate selection, etc.

1. VSM vibration sample magnetic strong measurement sensitivity can be 1 × 10-7EMU, please see Lakeshore company vibration sample magnetic strong meter website: http://www.lakeshore.com/product ... pages/overview.aspx [123
2. The principle of Squid is different from VSM
3. The price of two devices is much different. What do you want to do? If you mainly study the magnetic characteristics of the material, you need vsm

For our users, we only need to know the difference in accuracy. If the sample is weak, such as a film sample, the Squid is used. If the sample is strong, VSM is used, and the Squid test cost is high.

Compared with VSM, Squid mainly uses superconducting electromagnets, so the external magnetic field for testing can be several times larger.General VSM can be measured 2T, and Squid is just 7T. In addition, in terms of sensitivity, SQUID can theoretically measure a Bohlin, the smallest magnetic unit.For some people upstairs say that the accuracy of Squid to 10-6-side EMU, I think this VSM can also be achieved. As far as I know, the 7407 VSM of LakeShore can achieve this accuracy. If you have a test, you can contact me.Essence

Mainly the principle of signal production is different. VSM uses the law of Lenji to detect the induction voltage generated by the detection Squid is the Josephson knot effect, which belongs to the quantum effect, high sensitivity As for vibration, the new generation of QD's Squid-VSM is also vibratingMeasted.

The principle of signal collection of the two is different. VSM is a magnetic strength of the vibration sample. It is the magnetization strength of the sample by the change of the magnetic flux caused by the sample vibration of the sample in the signal coil. Squid is a superconductant sub-magnetic meter. The principle seems to be in solid physics. I forgot
From the perspective of accuracy level, the accuracy of Squid can be above 10-6emu, but the lower VSM is lower, Mainly used to measure the body.
