Exploring magnetic phases in a qubit Penrose quasicrystal

The fundamental dynamics of magnetic quasicrystals under an external magnetic field remains a challenging problem that could potentially impact the field design of information processing devices. Using a quantum annealer we built a qubit magnetic quasicrystal based on a Penrose tiling to inspect multiple magnetic textures at the individual-spin level driven by particular selections of physical parameters. In our experiments a broad range of frustrated magnetic configurations are observed as a result of the dynamical activation of some spins while others remain static. Static spin structure factors reveal ferromagnetic and ferrimagnetic modulations compatible with a wide range of spin textures. This study demonstrate that inducing multiple spins arrangements in one single object would offer the prospect of applications in magnetic memory storage by encoding multiple magnetic states in a same geometry.
