Inductance Versus Resistance

Can anyone advise me why the Inductance of a solenoid should change with rise in temperature.
Of course the resistance would change with temperature but I observe a change in the inductance measured with an LCR meter depending on the resistance.
Is there a formula which relates the solenoids inductance to it's resistance ?
Or perhaps is it possible that the permeability of the ferromagnetic materials surrounding the coil changes with temperature ?

In the case of iron;ess coil the coil's size changes with
temperature. Larger coil has higher inductance.

With iron core the core dominates.
