We investigate the possible effect of an ultra-strong magnetic field on the core matter, in particular quark matter inside a massive rotating neutron star. Based on the discovery “Evidence of quark matter cores in massive Neutron Stars” by Annala et al. our main motivation is to understand the type of structure formation that appears in the core of a rotating neutron star, magnetar. Taking into account two facts:

1. Free u, d, and s quarks can form a composite (i.e. quark matter composite) because of the seed magnetic field located inside the core of a massive neutron star, magnetar in analogy with the observed in the weapon “Bola” , and composite formation in a ferromagnetic liquid crystal;
2. Observation of sheet-like structure in ferromagnetic composites placed in a magnetic field having rotation,

we propose that a sheet-like structure might be appeared in the ferromagnetic quark matter composites inside the cores of massive rotating neutron stars , in particular a magnetar in the presence of its ultra-strong magnetic field which acts as catalyst.
