People are not the only ones to be occasionally frustrated. Some crystals also show frustrations. Cesium copper chloride is a prime example. Its magnetic copper atoms reside on a triangular lattice and seek to align themselves antiparallel to each other. In a triangle, this does not work, however. To better understand the underlying basics, physicists can now control the magnetic coupling using an elegant measuring method.
