$ZnFe_2O_4$

Vedclass · Answer

(D) Ferromagnetic substances are those that are strongly attracted by a magnetic field. $Fe_3O_4$ (magnetite) and ferrites like $MgFe_2O_4$ are examples of ferrimagnetic substances,which show strong attraction due to unequal alignment of magnetic moments. However,$ZnFe_2O_4$ is an example of an antiferromagnetic substance where the magnetic moments of the domains are aligned in such a way that they cancel each other out,resulting in zero net magnetic moment. $Fe_2O_3$ is also known to exhibit ferrimagnetism or antiferromagnetism depending on the phase. Among the given options,$ZnFe_2O_4$ is specifically classified as antiferromagnetic.
