Free radicals liquid used in magnetometer

[flm]

Hi all,

I am learning about magnetometers. Esp. those based on the Overhauser effect (https://en.wikipedia.org/wiki/Nuclear_Overhauser_effect). As I understand, they embed a free radical fluid that contains free electrons that gets polarized through a RF field. Do you have any idea what free radical liquid is used in commercial models ? I do not see any toxicity warning in datasheet I browsed so far (http://www.gemsys.ca/products/rugged-overhauser-magnetometer/)

Thanks a lot for your ideas !

Hello,

I am glad to hear that you are learning about magnetometers, specifically those based on the Overhauser effect. The Overhauser effect is a phenomenon in which the nuclear spins of certain atoms become aligned in the presence of an external magnetic field. This effect is used in magnetometers to measure magnetic fields.

In terms of the free radical fluid used in commercial models, it is typically a solution of nitroxide radicals. These radicals are relatively stable and non-toxic, which is why you did not see any toxicity warnings in the datasheet you browsed. However, it is always important to handle these solutions with care and follow proper safety precautions.

I hope this helps answer your question. If you have any further inquiries about magnetometers or other scientific topics, please do not hesitate to ask. Best of luck in your studies!
