Magnetic Moment: The magnetic moment of a magnet is a quantity that determines the force that the magnet can exert on electric currents and the torque that a magnetic field will exert on it. Magnetoelastic Anisotropy: tension may alter magnetic behavior, leading to magnetic anisotropy.Įxchange Anisotropy: a relatively new type that occurs when antiferromagnetic and ferromagnetic materials interact.Įasy Axis: An easy axis is an energetically favorable direction of spontaneous magnetization that is determined by the sources of magnetic anisotropy. Shape Anisotropy: when a particle is not perfectly spherical, the demagnetizing field will not be equal for all directions, creating one or more easy axes. Magnetocrystalline Anisotropy: the atomic structure of a crystal introduces preferential directions for the magnetization. Before elaborating the details of magnetic anisotropy, let’s get some knowledge about several related terms defined as the follows: Sources of Magnetic Anisotropy Magnetic anisotropy is the dependence of magnetic properties on a preferred direction.
