| Sumario: | We discuss the structure and evolution of a magnetized accretion disks around young stars that have dragged their magnetic eld in the process of gravitational collapse. The disk evolves due to two di usive processes: viscous stresses that redistribute mass and angular momentum, and the resistive di usion of mass across magnetic eld lines due to imperfect conduction. In steady-state there is an analytic model of the structure of these magnetized disks. We discuss the application of this model to disks around low and high mass young stars and recent results of time dependent models. |
