They are used to discuss some simple problems (a single spin in a field, a spin wave, two spin 1 / 2 particles with Heisenberg coupling) and it is shown that their use may often give increased physical insight.

Web$\begingroup$ @XinWang: Those are completely different uses of the word "coherent". A state of the harmonic oscillator which is an eigenstate of the annihilation operator is called a "coherent state". The word "coherent" also means a state which has off-diagonal elements in the density matrix. This can apply to spin or any other system.
