The magnetic moment of short lived β-emitter24mAl (426 keV,Iπ= 1+,T1/2= 131 ms) has been measured by means of β-NMR technique, for the first time. From the β-NMR spectrum, the magnetic moment was determined as $\left| {\upmu}\left( ^{\rm 24m}{\rm Al} \right) \right|=\left( {2.99\pm 0.09} \right){\upmu}_{\rm N}$. Combined with the known magnetic moment of the mirror partner24mNa, the expectation value of <Sz> is obtained to be (0.08 ± 0.12). These values are reproduced well by the shell model calculation.
