Bloch point structure

Bloch point structure in a magnetic nanosphere.
Oleksandr V. Pylypovskyi, Denis D. Sheka, and Yuri Gaididei
Phys. Rev. B 85, 224401 (2012)

Dynamics of total spin along the z axis of the sample. The Bloch point is initially shifted by Δz=−2a0 from the center of the sample. The insets show magnetization distribution in z=−0.5a0 and y=−0.5a0 planes for different times. The color bar indicates Sz,n for different lattice nodes.

EJPB 82, 159 (2011)
Comparison of the Bloch point evolution with fixed magnetization at the surface of a sphere of radius
larger than the exchange length R = 20 nm; times are: (left) t = 0, (middle) t = 80 ps, and (right) t = 160 ps.
