Solution

For Diamagnetic materials, xm < 0
For paramagnetic materials, xm > 0
For superparamagnetic materials, xm >>0

(i) if xm =-0.00015 < 0, the material is Diamagnetic.

(ii) if xm = 10-5 > 0, the material is paramagnetic because the value of susceptibility is greater than zero but has a very small value.
