共面多铁性材料中的自旋超流性
Spin Superfluidity in Coplanar Multiferroics
摘要:
讨论了超流凝聚体中的共面磁序多铁性,特别强调了凝聚体的相位梯度和外部电场的影响所产生的自旋超流。通过绘制类比的超导凝聚体,现象,如持续电流环,Little-Parks效应,磁通量子化,约瑟夫森通过自旋畴壁的影响,并在SQUID的几何形状的干涉行为进行了分析共面多铁性。
英文摘要:
Multiferroics with coplanar magnetic order are discussed in terms of a superfluid condensate, with special emphasis on spin supercurrents created by phase gradients of the condensate and the effect of external electric fields. By drawing the analogy to a superconducting condensate, phenomena such as persistent currents in rings, the Little-Parks effect, fluxoid quantization, the Josephson-like effect through spin domain walls, and interference behavior in a SQUID-like geometry are analyzed for coplanar multiferroics.
