AB  - Spin relaxation results in the spin decoherence and a finite spin lifetime, which are detrimental to spintronic devices. To achieve a long spin lifetime desirable for spintronic devices, elucidating the spin relaxation mechanism and factors influencing the spin lifetime is of vital importance. Here, we investigate the spin relaxation in X-wave magnets (X=p, d, f, g, i) with Rashba spin-orbit coupling within the framework of D'yakonov-Perel' mechanism. We calculate the general matrix of the spin relaxation time for an arbitrary Néel vector direction of the X-wave magnet. As an illustration, we study the spin relaxation for the Néel vector along the [001] direction. It is found that the reciprocal spin-relaxation-time matrices are anisotropic and diagonal for the d-, f-, g- and i-wave magnets. For the p-wave magnet, we derive the analytical expressions for the temporal evolution of spins. Moreover, the spin relaxation rate is proportional to the momentum relaxation time, Rashba and altermagnetic spin-split strengths for all X-wave magnets. Our results shine more light on the fundamental understanding of the spin relaxation mechanism in X-wave magnets.
