Magnetic refrigeration absolute zero
WebCryogenics: Low temperatures, high performance. CERN's cryogenic systems cool over 1000 magnets on the LHC to temperatures close to absolute zero, where matter takes … WebFor the entropy at absolute zero to be zero, the magnetic moments of a perfectly ordered crystal must themselves be perfectly ordered; from an entropic perspective, this can be considered to be part of the definition of a "perfect crystal". Only ferromagnetic, antiferromagnetic, and diamagnetic materials can satisfy this condition.

Your misunderstanding is here: I know that atoms will no longer move at absolute zero so I was wondering if that means they will not attract towards one another either. First of all, it isn't quite true that all motion stops at ...

WebSep 11, 2003 · At absolute zero (-273 degrees C or -460 degrees F), all atomic motion comes to a standstill since the cooling process has extracted all the particles' energy. By improving cooling methods, scientists have succeeded in getting closer and closer to absolute zero. At room temperature, atoms move at the speed of a jet airplane.
