We studied the 3d Heisenberg site disordered model with and without weak random anisotropy D in the presence of a uniform external longitudinal magnetic field using Monte Carlo methods. The spin and the chirality correlation lengths were measured. The study provided evidence that the mixed chiral phase is a chiral glass at a finite temperature transition TCG > 0, whereas the spin glass temperature transition is at T-SG = 0 for D = 0. In the anisotropic case, the model exhibited strong evidence of finite temperature transitions in both the spin and the chirality sectors. The estimated spin and chirality correlation-length exponents were compatible with the previous values obtained for the same model without anisotropy and the 3d Heisenberg spin glass.
