What does negative to positive transition of magnetoresistance indicate?

I have a semiconducting material that is diamagnetic in nature. On doping with magnetic ions, it shows paramagnetic behaviour. Further on substituting a non-magnetic ion into the system, it shows...

Resistivity of a semiconductor in MegaOhm-cm range due to transition metal doping

Is it possible that a semiconductor when doped with transition metal may have its resistivity in the MegaOhm-cm range? The resistivity of the material without doping is however between 0.9 - 1 Ohm-cm.
