i am trying to understand the magnetocaloric effect from another point of view (besides thermodynamics ) , i know that under the influence of an external field , a zeeman splitting happens , and the electrons will have different levels of energy , those with + 1/2 spin will have a higher energy than those with -1/2 . is this separation what causes an increase in temperature ? , i know that after the zeeman splitting, a variation in the distribution will occur , the electrons with + 1/2 spin , will try to lower their energy to the same level as -1/2 electrons , by releasing releasing thermal energy . doesn't that mean they will get cooler ? can someone please enlighten me ? thank you very much in advance .
