▁magnet ization ▁will ▁f lip ▁several ▁times ▁during ▁the ▁measurement . ▁In ▁zero ▁field , ▁the ▁measured ▁magnet ization ▁will ▁average ▁to ▁zero . ▁If ▁, ▁the ▁magnet ization ▁will ▁not ▁f lip ▁during ▁the ▁measurement , ▁so ▁the ▁measured ▁magnet ization ▁will ▁be ▁equal ▁to ▁the ▁initial ▁magnet ization . ▁In ▁the ▁former ▁case , ▁the ▁nan op article ▁will ▁appear ▁to ▁be ▁in ▁the ▁super param agnet ic ▁state ▁whereas ▁in ▁the ▁latter ▁case ▁it ▁will ▁be ▁blocked ▁in ▁its ▁initial ▁state . ▁The ▁state ▁of ▁the ▁nan op article ▁( super param agnet ic ▁or ▁blocked ) ▁depends ▁on ▁the ▁measurement ▁time . ▁A ▁transition ▁between ▁super param agnet ism ▁and ▁the ▁blocked ▁state ▁occurs ▁when ▁. ▁In ▁several ▁experiments , ▁the ▁measurement ▁time ▁is ▁kept ▁constant ▁but ▁the ▁temperature ▁is ▁varied , ▁so ▁the ▁transition ▁between ▁super param agnet ism ▁and ▁blocked ▁state ▁is ▁a ▁function ▁of ▁the ▁temperature . ▁The ▁temperature ▁for ▁which ▁ ▁is ▁called ▁the ▁blocking ▁temperature : ▁ ▁For ▁typical ▁labor atory ▁measurements , ▁the ▁value ▁of ▁the ▁log arith m ▁in ▁the ▁previous ▁equation ▁is ▁in ▁the ▁order ▁of ▁ 2 0 – 2 5 . ▁ ▁References ▁ ▁Category : Mag net ism ▁Category : Non - equ ilib rium ▁therm od ynam ics <0x0A> </s> ▁María ▁del ▁C is ne ▁River a ▁Ál vare z ▁( born ▁April ▁ 2 7 , ▁ 1 9 9 6 ▁in ▁C uen ca ) ▁is ▁an ▁E cuador ian ▁model , ▁Miss ▁Te en
