  We investigate the possibility of the existence of the exotic torus
configuration in the high-spin excited states of $^{40}$Ca. We here consider
the spin alignments about the symmetry axis. To this end, we use a
three-dimensional cranked Skyrme Hartree-Fock method and search for stable
single-particle configurations. We find one stable state with the torus
configuration at the total angular momentum $J=$ 60 $\hbar$ and an excitation
energy of about 170 MeV in all calculations using various Skyrme interactions.
The total angular momentum J=60 $\hbar$ consists of aligned 12 nucleons with
the orbital angular momenta $\Lambda=+4$, +5, and +6 for spin up-down neutrons
and protons. The obtained results strongly suggest that a macroscopic amount of
circulating current breaking the time-reversal symmetry emerges in the
high-spin excited state of $^{40}$Ca.
