The Cd 1− x Mn x Te (x= 0–0.18) nanowires were grown using a wet-chemical synthesis. The synthesized Cd 1− x Mn x Te nanowires have diameters in the range of 50–100 nm and display zinc-blend crystal structure. In bulk, Cd 1− x Mn x Te is extensively studied, but the difficulty in doping Mn in CdTe nanowires delayed the understanding of the properties at the nanoscale. The authors have used a cation exchange method to incorporate Mn in CdTe nanowires. Their magnetic behavior can be tuned by varying the concentration of Mn ions. The CdTe nanowires were paramagnetic while doping small amount of Mn ions introduces ferromagnetic behavior at low temperatures. As the manganese concentration is increased in CdTe, both spin glass and antiferromagnetic behaviors are observed. This is in contrast to what is observed in bulk, where only paramagnetic behavior is observed for x< 0.17.
