The dependence of the subtitle is studied on the magnetic-field-induced SDW (FlSDW) and the transient type of SDW (SDW2) in the boundary region around theparameter region of the stable SDW on the basis of numerical computation of theground state energy and consideration on the electronic structure. Reversal of the current carrier type on appearance of the Fl-SDW and SDW2 is clarified with realisticvalues of the parameter set. The amount of energy gain due to the orbital quantizalion in the field is improved. Although the field-dependence of magnetization is not soimproved, the average period of transitions among the Fl-SDW subphases is found inthe accessible range of reasonable models. There appear new features of the phasediagram such as jump of the magnetic quantum number by more than one and aphase boundary between zones of positive and negative shil'ts of Q,.
