The temperature dependence of the first anisotropy constant of the garnet system Y<sub>3</sub>Fe<sub>5-x</sub>Mn<sub>x</sub>O<sub>12</sub> (x=0.006, 0.043) is reported. From the experimental results the single Mn<sup>3+</sup> ion contribution k<sub>1</sub> to the anisotropy constant is deduced and analysed. It is shown that the observed large and positive values of k<sub>1</sub> may be explained on the basis of the existing theory of the Jahn-Teller effect of the octahedrally coordinated Mn<sup>3+</sup> ion.
