A magnetocaloric study of the magnetostructural transitions in NiCr${}_2$O${}_4$

Anzar Ali, Gyaneshwar Sharma, Yogesh Singh

The spinel NiCr${}_2$O${}_4$ is known to show a ferrimagnetic transition at $T_c=70$~K, and magneto-structural transitions at $T_s=30$~K and $T_o=20$~K\@. We present a detailed m…
