How do Cesium gas atoms demagnetise

In summary, the conversation discusses the decay profile of magnetized Cs atoms and the equations that govern this behavior. The speaker requests a reference for further information on NMR and the classical equations that involve two time constants, T1 and T2.

Hello guys :),

if we magnetise Cs atoms with a magnetic field (or basically any other method like pumping), and got all the spins (moments) aligned in 1 direction, and then turn the cause of the alignment off, how will the decay profile look like? is it going to be a clean exponential decay? what are the equations governing this behavior?

I don't really know where to start with the answer to this.

I would appreciate an answer, reference, essay, article, book, or whatever kind of help you may provide me :-)

Thank you for any efforts :-)

You should probably try to find a book about NMR.
In the "classical" equations for this you end up with two time constants (T1 and T2) which govern the relaxation and the dephasing.

Thank you for your reply.

Could you please mention some specific book?

Related to How do Cesium gas atoms demagnetise

1. How does Cesium gas become magnetized in the first place?

Cesium gas can become magnetized through exposure to a strong magnetic field, which aligns the electron spins in the gas atoms in a specific direction.

2. What factors affect the rate of demagnetization in Cesium gas?

The rate of demagnetization in Cesium gas can be affected by the strength and direction of the external magnetic field, as well as the temperature and pressure of the gas.

3. Can Cesium gas atoms demagnetize on their own, without exposure to an external magnetic field?

Yes, Cesium gas atoms can demagnetize on their own through a process called spin relaxation, where the electrons in the gas atoms randomly change their spin directions over time.

4. How long does it take for Cesium gas atoms to demagnetize?

The rate of demagnetization in Cesium gas can vary depending on the factors mentioned above, but typically it can take anywhere from milliseconds to several minutes for the gas atoms to fully demagnetize.

5. What applications does the demagnetization of Cesium gas have in science and technology?

The demagnetization of Cesium gas is important in fields such as atomic clocks, quantum computing, and nuclear magnetic resonance imaging (MRI) technology. It also has applications in the study of fundamental physics and magnetic materials.
