Magnetic moment and magnetic properties

[Suraj M]

Homework Statement

Mn⁺² has a higher magnetic moment than Fe⁺² but practically Fe⁺² is ferromagnetic right? So more magnetic right?

Homework Equations

$μ = √ (n(n+1))$[/B]

The Attempt at a Solution

For the Mn ion it comes to be √35 and for the ferrous ion √25
So yes Mn⁺² is more paramagnetic but Fe⁺² is more magnetic as a solid right?
I really don't know why
Could it be the alligator of the atoms in the solid?

 

[DrDu]

Metallic solid iron is ferromagnetic and this is a complicated effect involving the interaction of the atoms. It makes no sense to say that ferrous ions are ferromagnetic.

Ok Between Fe2+ or Mn2+
Which one produces a stronger magnetic field? Fe2+ right?
