In this work we investigate magnetic hexadecapole (M4) NMEs in medium-heavy nuclei. The experimentally derived NMEs, <math id=\"M2\"><mrow><msub><mrow><mi>M</mi></mrow><mrow><mi>E</mi><mi>X</mi><mi>P</mi></mrow></msub></mrow></math>(M4), deduced from observed M4 <math id=\"M3\"><mrow><mi>\u03b3</mi></mrow></math> transition half-lives are compared with the single-quasiparticle (QP) NMEs, <math id=\"M4\"><mrow><msub><mrow><mi>M</mi></mrow><mrow><mi>Q</mi><mi>P</mi></mrow></msub></mrow></math>(M4), and the microscopic quasiparticle-phonon model (MQPM) NMEs <math id=\"M5\"><mrow><msub><mrow><mi>M</mi></mrow><mrow><mi>M</mi><mi>Q</mi><mi>P</mi><mi>M</mi></mrow></msub></mrow></math>(M4). The experimentally derived M4 NMEs are found to be reduced by a coefficient <math id=\"M6\"><mi>k</mi><mo>\u2248</mo><mn>0.29</mn></math> with respect to <math id=\"M7\"><mrow><msub><mrow><mi>M</mi></mrow><mrow><mi>Q</mi><mi>P</mi></mrow></msub></mrow></math>(M4) and by <math id=\"M8\"><mi>k</mi><mo>\u2248</mo><mn>0.33</mn></math> with respect to <math id=\"M9\"><mrow><msub><mrow><mi>M</mi></mrow><mrow><mi>M</mi><mi>Q</mi><mi>P</mi><mi>M</mi></mrow></msub></mrow></math>(M4). The M4 NMEs are reduced a little by the quasiparticle-phonon correlations of the MQPM wave functions but mainly by other nucleonic and nonnucleonic correlations which are not explicitly included in the MQPM. The found reduction rates are of the same order of magnitude as those for magnetic quadrupole <math id=\"M10\"><mrow><mi>\u03b3</mi></mrow></math> transitions and Gamow-Teller (GT) and spin-dipole (SD) <math id=\"M11\"><mrow><mi>\u03b2</mi></mrow></math> transitions. The impacts of the found reduction coefficients on the magnitudes of the NMEs involved in astroneutrino interactions and neutrinoless double beta decays are discussed."
