Impact of amorphization on the magnetic state and magnetocaloric properties of Gd3Ni

Ball milling as a way to produce magnetic and magnetocaloric materials: a review

“…From Eq. (17) it is observed that, for values well below TC, nmain=1, there is no effect of the presence of ferromagnetic impurities in the field dependence of MCE response. As temperature increases approaching TC, nmain<1 and thus, the value of the experimental ntotal>nmain.…”

“…Therefore, taking into account Eq. (17), the effect of the impurities on ntotal will be bigger as temperature increases. In fact, well above the transition, where nmain=2, the trend of ntotal should exhibit a monotonous decrease.…”

“…The ability of BM to produce alloys and complexes via mechanical alloying or mechanochemical reactions makes this technique attractive to produce many different systems, such as Gd-based amorphous alloys [15][16][17], Fe-based amorphous alloys [18][19][20], Co-based amorphous alloys [21], FeNi metastable phases [22][23][24][25], Heusler alloys [26], oxides [27][28][29], maganites [30,31] and, recently, Gd-based borohydrides prepared by a mechanochemistry route [32].…”
