“…These ideas have recently received much experimental and theoretical attention as a suitable spin source for spintronic devices, such as spin transistors, light emitting diode (LEDs), magnetic random access memory (RAMs), and magnetic sensors . The advantages of these new devices would be nonvolatility, increased data processing speed, decreased electric power consumption, and increased integration densities compared with conventional semiconductor devices . Furthermore, II‐VI semiconductor compounds doped with TM are more favorable than III‐V, because of the lack of solubility .…”

A series of Zn 1−x Co x Se (x = 0, 0.025, 0.050, 0.075, and 0.100) films using were evaporated (thickness of 1 μm) using electron beam gun. The effect of Co doping on the structural, optical, and magnetic properties has been investigated. X-ray diffraction studies confirm formation of zinc blend structure for all Zn 1−x Co x Se films. The crystallite size increases and the lattice strain decreases with the increase in Co content. The elemental constituents were characterized by energy dispersive X-ray. Optical studies showed an increase in refractive index and a decrease in energy gap with the increase in the cobalt doping. The dispersion of the refractive index has been analyzed in terms of the Wemple-DiDomenico single oscillator model. The oscillator parameters including the single oscillator energy (E o ), the dispersion energy (E d ), and the static refractive index (n 0 ) were estimated. Magnetization measurements via vibrating sample magnetometer showed a hysteresis loop and confirmed room-temperature ferromagnetism in Co-doped ZnSe films.
