Room-temperature ferromagnetism in Mn-doped semiconducting CdGeP2.
نویسندگان
چکیده
The chalcopyrite CdGeP2 doped with Mn have been recently found to exhibit room-temperature ferromagnetism. Isovalent substitution of the Cd site is expected, however, to create antiferromagnetism, in analogy with the well-known CdTe:Mn (d5) case. However, chalcopyrite semiconductors exhibit low-energy intrinsic defects. We show theoretically how ferromagnetism results from the interaction of Mn with hole-producing intrinsic defects.

Electric-field control of ferromagnetism in magnetic semiconductors at room temperature has been actively pursued as one of the important approaches to realize practical spintronics and non-volatile logic devices. While Mn-doped III-V semiconductors were considered as potential candidates for achieving this controllability, the search for an ideal material with high Curie temperature (T(c)>300 ...

Magnetic and magneto-optical properties were measured at room temperature in the Mn-diffused surface layer of a CdGeP2 single crystal. The magnetization curve measured using VSM clearly shows a ferromagnetic hysteresis loop with Hc=0.4 kOe superposed on the diamagnetic component. The ferromagnetic Curie temperature was determined as 320 K from the magnetization vs. temperature curve. The magnet...
