最近,我们已经表明,各向异性的Anderson-Morel态可以通过在自旋涨落谱中引入能隙所产生的有效相互作用中的反馈效应来稳定。在本文中,我们确定了由于上述机制的自由能中的四阶项的一般形式,并使用这个结果来预测在磁场存在下的相图,并作为压力的函数。(auth)
Recently we have shown that an anistropic Anderson-Morel state may be stabilized by feedback effects in the effective interaction arising from introduction of a gap in the spin-fluctuation spectrum. In this paper we determine the general form of the fourth-order term in the free energy owing to the above mechanism and uses this result to make predictions regarding the phase diagram in the presence of a magnetic field and as a function of pressure.
