Just interested to know what the flux saturation of gadolinium is, and what is its Curie temperature?
I can't find any data on it at all.
thanks.

I did a Google search on your thread title, and seem to get good hits. Have you seen these already?cmb said:The hits I get are all about MRI, due to the gadolinium marker they use for some scans, and I can't search for anything beyond that.
Yes, they are all showing as 'opened' in the usual browser colour on my computer, I have already gone through those.berkeman said:I did a Google search on your thread title, and seem to get good hits. Have you seen these already?

If that info is correct, it is paramagnetic at room temperature =## 20^{\circ} ## C, but will be ferromagnetic if you go to cool "room" temperatures=## T<60^{\circ} ## F. ## \\ ## If you can get a sample, it should be interesting for you to experiment with the temperature phase change.cmb said:http://academic.uprm.edu/pcaceres/Courses/Smart/SMD-7A.pdf
Slide 31/76 appears to say it is 2.5T, Curie temp 16C. I presume a piece at [warm] room temperature is therefore not ferromagnetic at all but paramagnetic?
Magnetic saturation refers to the point at which a material can no longer be magnetized, meaning that it has reached its maximum magnetic field strength. This is typically measured in units of Tesla (T) or Gauss (G).
Gadolinium is a rare earth metal with the atomic number 64. It is a silvery-white metal that is commonly used in alloys and in the production of electronic components. It is also known for its unique magnetic properties.
The magnetic saturation of gadolinium is typically measured using a magnetometer, which is a device that can detect and measure magnetic fields. The material is placed in a magnetic field and the resulting magnetization is measured, allowing for the determination of its magnetic saturation point.
The magnetic saturation of gadolinium is important because it is one of the highest among all elements, making it useful for various applications such as in magnetic resonance imaging (MRI) machines, magnetic refrigeration, and magnetic data storage. Its high magnetic saturation also makes it a valuable component in alloys used for high-strength magnets.
Yes, the magnetic saturation of gadolinium can be changed by altering its temperature or by applying an external magnetic field. At low temperatures, gadolinium exhibits a phenomenon called the "magnetic phase transition" where its magnetic properties change significantly. Additionally, applying a strong magnetic field can also increase the magnetic saturation of gadolinium.
