Question

I'm quite sure about this one, but anyone who can verify this?

Am I correct in stating that the ZnFe2O4 spinel (ZnO:Fe2O3) is not ferrimagnetic due to the fact that Zn2+ is a diamagnetic ion (completely filled d shell).

Answer 1

you are correct

Answer 2

i don't see why Fe(III) wouldn't be paramagnetic, I'm not sure what kind of geometry this has though.

Answer 3

hi

Answer 4

Fe3+ is paramagnetic. The question is wether the compound can be ferrimagnetic, ie have alternating planes (zn2+ and fe3+) with opposite spins, but not equal. I am saying that the zn2+ plane cant have any net spin cause zn2+ is diamagnetic.

Answer 5

sounds good
