• Langevin dynamics method was applied based on the effective Verlet-type algorithm. The Néel magnetic relaxation time was obtained via the Coffey method in an oblique magnetic field, adapted to the local magnetic field on a nanoparticle.

• method, based on an effective Verlet-type algorithm [19]. The Néel magnetic relaxation time is obtained through the Coffey method in an oblique magnetic field, adapted to the local magnetic field of a nanoparticle [22][23]. For each nanoparticle, the effective magnetic relaxation time can be described

• Equation 4. To solve the equations of motion numerically we use the effective Verlet-type algorithm [20][21]. The Coffey method in an oblique magnetic field adapted to the local magnetic field on a nanoparticle According to the literature, as a general rule, the Néel–Brown model is used to obtain the Néel
