In magnetization dynamics, the relaxation is driven by the damping. Here, we demonstrate that damping in exchange-coupled systems is not only anisotropic but also unidirectional evidenced by an asymmetry in the damping by inversion of the magnetic field polarity. Our study reveals that this asymmetry in the damping is enhanced by the increase in the exchange bias field. Finally, we introduce a modified relaxation term in the equation of motion.
