  We investigate the memory effects associated with the kicks of particles.
Recently, the equivalence between the memory effect and soft theorem has been
established. By computing the memory effect from the radiation solutions, we
explicitly confirm that, in addition to the leading piece, the subleading and
subsubleading soft theorems are equivalent to the subleading and subsubleading
memory effects, respectively. It is known that the memory effects can be probed
by the displacements or kicks of the test particles. We point out that the
these memory effects are also probed by the permanent change of the direction
of the spin. We also show that the axion memory effect, recently proposed by
the current authors, can be detected as the change of the spin of the test
particle. We discuss that if we consider the magnetic monopole as an external
particle, the parity-odd electromagnetic memory appears.
