It is widely believed that magnetic fields play an important role in the early stages of star formation (McKee \& Ostriker 2007, Crutcher 2012). Particularly, magnetic braking can remove angular momentum efficiently and has been widely considered in theoretical models of disk formation (Li et al. 2014, PPIV, and the reference therein). However, several Class 0 disks have been found and new theoretical models also suggest that disks can form under the influence of turbulence and non-MHD effects.
In this talk, I will present recent observations of magnetic fields toward Class 0 sources that may have shed some light on this important question.
