Query: Magnetic Tetrastability in a Spin Chain   Bistability in magnetism has been extensively used, in particular to store
information. Here we propose an alternative route by using tetrastable magnetic
domains. Using numerical and analytical calculations we show that a spin chain
with a canting angle of {\pi}/4 possesses four energy-equivalent states. We
discuss the static properties of such chain such as the profile and the energy
of the domain walls as they govern the relaxation of the magnetization. The
realisation of such spin chain could enable the encoding of the information on
four bits which is a potential alternative toward the increase of storage
density.
