## Description

- description: Understanding magnetocrystalline anisotropy (MCA) is fundamentally
    important for developing novel magnetic materials. Therefore, clarifying the relationship
    between MCA and local physical quantities observed by spectroscopic measurements,
    such as the orbital and quadrupole moments, is necessary. In this review, we discuss
    MCA and the distortion effects in magnetic materials with transition metals (TMs)
    based on the orbital and quadrupole moments, which are related to the spin-conserving
    and spin-flip terms in the second-order perturbation calculations, respectively.
    We revealed that orbital moment stabilized the spin moment in the direction of
    the larger orbital moment, while the quadrupole moment stabilized the spin moment
    along the longitudinal direction of the spin-density distribution. The MCA of
    the magnetic materials with TMs and their interfaces can be determined from the
    competition between these two contributions. We showed that the perpendicular
    MCA of the face-centered cubic Ni with tensile tetragonal distortion arose from
    the orbital moment anisotropy, whereas that of Mn-Ga alloys originated from the
    quadrupole moment of spin density. In contrast, in the Co/Pd(111) multilayer and
    Fe/MgO(001), both the orbital moment anisotropy and quadrupole moment of spin
    density at the interfaces contributed to the perpendicular MCA. Understanding
    the MCA of magnetic materials and interfaces based on orbital and quadrupole moments
    is essential to design MCA of novel magnetic applications.
