摘要:

反铁磁体在磁振子学领域引起了广泛关注,因其有望成为未来计算中信息传输的超低能耗载体候选材料。晶体取向分布对磁振子输运的作用却很少受到关注。在 BiFeO$_3$ 等多铁性材料中,反铁磁序与极性序之间的耦合为自旋输运施加了又一边界条件。因此,理解此类体系中自旋输运的基础需要一个单畴、单晶。我们表明,通过镧(La)取代,可以构筑出具有稳定、单一变体自旋摆线的单一铁电畴,并且该自旋摆线可由电场控制。这种单畴中的自旋输运表现出强烈的各向异性,其源于底层的自旋摆线晶格。我们的工作展示了一条理解此类单畴多铁性材料中自旋输运根本起源的途径。

英文摘要:

Antiferromagnets have attracted significant attention in the field of magnonics, as promising candidates for ultralow-energy carriers for information transfer for future computing. The role of crystalline orientation distribution on magnon transport has received very little attention. In multiferroics such as BiFeO$_3$ the coupling between antiferromagnetic and polar order imposes yet another boundary condition on spin transport. Thus, understanding the fundamentals of spin transport in such systems requires a single domain, a single crystal. We show that through Lanthanum(La) substitution, a single ferroelectric domain can be engineered with a stable, single-variant spin cycloid, controllable by an electric field. The spin transport in such a single domain displays a strong anisotropy, arising from the underlying spin cycloid lattice. Our work shows a pathway to understand the fundamental origins of spin transport in such a single domain multiferroic.
