We report on the first measurement of the g factor of the Jpi = 9/2+ isomeric state in $^{65}$Ni. (d,p) reactions on enriched $^{64}$Ni and 62Ni have been used in order to populate and spin orient the Jpi = 9/2+ isomeric states in 65Ni and 63Ni. The hyperfine field of the Ni target, oriented by an external magnetic field, was used in order to obtain a sufficient number of spin precessions within the relatively short life time of the isomers. The g factor obtained, g65mNi = -0.296(3), is in good agreement with the g factors of other 9/2+states in the region and with shell-model calculations.
