Deskripsi

Skyrmion bubbles consist of a centre magnetization pointing up or down, and a swirling vortex magnetic texture, either clockwise or anticlockwise around this. Here, Yao et al use a three-dimensional imaging approach to study this magnetic texture, and show that while the in-plane vortex-like texture changes easily, the centre magnetic direction, the polarity, is retained, leading to a reversed chirality.
