摘要翻译：
实验研究了二维排斥芯软化球的凝聚相。超顺磁球间的偶极对排斥作用是由横向磁场引起的，通过适当地调节超顺磁球胞的厚度可以使其减弱。我们扫描了一个很宽的密度范围，我们在核心软化粒子系统中实现了理论预测的大部分相，包括膨胀和紧密堆积的六方相、方形相、链状相、条纹/迷宫相和蜂窝相。蒙特卡罗模拟提供了对它们结构的进一步了解。

英文摘要：
We experimentally study the condensed phases of repelling core-softened spheres in two dimensions. The dipolar pair repulsion between superparamagnetic spheres trapped in a thin cell is induced by a transverse magnetic field and softened by suitably adjusting the cell thickness. We scan a broad density range and we materialize a large part of the theoretically predicted phases in systems of core-softened particles, including expanded and close-packed hexagonal, square, chain-like, stripe/labyrinthine, and honeycomb phase. Further insight into their structure is provided by Monte Carlo simulations.
