  Single crystal of CeMg$_{12}$ is obtained by Bridgman method. CeMg$_{12}$
crystallizes in the tetragonal structure with space group $I4/mmm$ (#139). The
Laue pattern confirms the tetragonal crystal structure of CeMg$_{12}$. We have
studied the magnetic properties by measuring magnetic susceptibility,
magnetization, heat capacity and electrical transport. Specific heat
measurement shows that the compound orders at 1.2 K. We have measured the
magnetic susceptibility in the temperature range 1.8 to 300 K, and the
susceptibility data show that [100] crystallographic direction is the easy axis
of magnetization. At high temperature inverse susceptibility varies linearly
with temperature, and follows the Curie-Weiss behaviour. The effective moment
is close to the free ion value thus indicating Ce is in trivalent state in this
compound.
