Аннотация:A simple method for calculating the electronic structure of antiferromagnetic chromium with a sinusoidal spin-density wave, based on the variational Ritz procedure, is suggested. The four-component Dirac wavefunctions, defined in a crystal without allowance for magnetic order, are chosen as basis functions. The calculations of the electronic spectrum of chromium performed for different types of spin-density wave polarization show that taking into account the relativistic effects results in a difference between the electronic structures of the longitudinal and transverse spin-density waves.
