  Single crystal of CeAl has been grown by flux method using Ce-Al self-flux.
Several needle like single crystals were obtained and the length of the needle
corresponds to the [001] crystallographic direction. Powder x-ray diffraction
revealed that CeAl crystallizes in orthorhombic CrB-type structure with space
group ${Cmcm}$ (no. 63). The magnetic properties have been investigated by
means of magnetic susceptibility, isothermal magnetization, electrical
transport, and heat capacity measurements. CeAl is found to order
antiferromagnetically with a N$\grave{\rm e}$el temperature $T_{\rm N}$ = 10K.
The magnetization data below the ordering temperature reveals two metamagentic
transitions for fields less than 20kOe. From the inverse magnetic
susceptibility an effective moment of $2.66\mu_{\rm B}$/Ce has been estimated,
which indicates that Ce is in its trivalent state. Electrical resistivity data
clearly shows a sharp drop at 10K due to the reduction of spin disorder
scattering of conduction electrons thus confirming the magnetic ordering. The
estimated residual resistivity ratio (RRR) is 33, thus indicating a good
quality of the single crystal. The bulk nature of the magnetic ordering is also
confirmed by heat capacity data. From the Schottky anomaly of the heat capacity
we have estimated the crystal field level splitting energies of the $(2J+1)$
degenerate ground state as 25K and 175K respectively for the fist and second
excited states.
