Abstract

Thermodynamic properties of strange quark matter are considered in strong magnetic fields up to 1020 G. It is shown that the appearance of the longitudinal (along the magnetic field) instability beyond some critical magnetic field precludes the formation of fully polarized quark states in strange quark matter as well as prevents a significant drop of strangeness which, otherwise, could happen in such ultrastrong magnetic fields.
