標題: | Proposed third long-range order in multiferroics | 作者: | CHONG-DER HU | 公開日期: | 2010 | 卷: | 81 | 期: | 22 | 來源出版物: | Physical Review B - Condensed Matter and Materials Physics | 摘要: | We proposed that in multiferroics, there exists a third long-range order besides the electric polarization and magnetic order. This long-range order reduces the symmetry of the spatial part of the wave functions of electrons. Thus the cancellation in the "spin-current" model can be avoided. As a result, the expectation value of electric polarization will be larger by an order of magnitude. We have derived a distinct form of electric polarization P- ∼- × ( sj ×sj+1), where Q- is the wave vector of this long-range order. © 2010 The American Physical Society. |
