Abstract Magnetic phases of holmium films are associated with the intensity of the magnetic neutron scattering. It is shown that each magnetic phase of the system (fan, helifan, spin-slip, helix and ferromagnetic) exhibits a characteristic profile of scattering which can be used as a fingerprint to identify it. In this paper, we present theoretical results obtained for holmium films 24 monolayers thick at a fixed temperature and in the presence of a dc magnetic field applied along the basal plane. A self-consistent local field algorithm was used to obtain the equilibrium configurations of the magnetic moments of the film and, with these results, the spin-spin correlation functions which determine the shape of the neutron scattering intensity were calculated.

通过磁中子散射表征钬纳米膜的磁相

摘要 钬薄膜的磁相与磁中子散射强度有关。结果表明，系统的每个磁相（扇形、螺旋形、自旋滑移、螺旋和铁磁）都表现出散射的特征轮廓，可用作识别它的指纹。在本文中，我们提出了在固定温度和沿基面施加直流磁场的情况下，24 单层厚的钬膜获得的理论结果。自洽局部场算法用于获得薄膜磁矩的平衡配置，并根据这些结果计算确定中子散射强度形状的自旋-自旋相关函数。
