We consider a low-temperature plasma within a newly developed magnetohydrodynamic fluid model. Inaddition to the standard terms, the electron spin, quantum particle dispersion, and degeneracy effects areincluded. It turns out that the electron spin properties can give rise to ferromagnetic behavior in certainregimes. If additional conditions are satisfied, a homogeneous magnetized plasma can even be unstable. Thishappens in the low-temperature high-density regime, when the magnetic properties associated with the spin canovercome the stabilizing effects of the thermal and Fermi pressure, to cause a Jeans-like instability.
