  The spontaneous generation of magnetic and chromomagnetic fields at high
temperature in the minimal supersymmetric standard model (MSSM) is
investigated. The consistent effective potential including the one-loop and the
daisy diagrams of all bosons and fermions is calculated and the magnetization
of the vacuum is observed. The mixing of the generated fields due to the quark
and s-quark loop diagrams and the role of superpartners are studied in detail.
It is found that the contribution of these diagrams increases the magnetic and
chromomagnetic field strengths as compared with the case of a separate
generation of fields. The magnetized vacuum state is found to be stable due to
the magnetic masses of gauge fields included in the daisy diagrams.
Applications of the results obtained are discussed. A comparison with the
standard model case is done.
