Spin relaxation mechanisms were studied under varying transverse magnetization and pulse conditions in graphene. The study reveals a single continuous time scale for spin relaxation (>70 ps), diverging from previous two-time-scale models. Spin transitions and magnetic asymmetries were analyzed through transient reflectivity, revealing Gaussian and quasi-equilibrium states. Results highlight the independence of magnetic moment from pulse intensity beyond certain thresholds and propose doping to modulate electron dynamics in graphene. femtosecond spin dynamics, Schrödinger, Bloch NMR, spin relaxation https://creativecommons.org/licenses/by/4.0/
