What is Phase Transition in II–VI Nanofilms of Dilute Magnetic Semiconductors: Cd~1– x ~Ni ~ x ~S about?

Phase transition from diamagnetic behavior to para/weak ferromagnetism in Cd 1-x Ni x S for 0 ≤ x ≤ 0.09 nanofilms was investigated by grazing angle x-ray diffraction (GXRD) and vibrating sample magnetometer (VSM). M-H curves clearly show negative magnetic susceptibility (χ m ) for x < 0.06 and for x ≥ 0.06 it changes sign. This is due to increase in nonequilibrium states for unpaired d-orbital electrons with increasing Ni concentration.
