    • Disclosed herein is a method of manufacturing a color-controlled sapphire, comprising: vaporizing a metal material, irradiating the vaporized metal material with electron beams or high-frequency waves to form the vaporized metal material into a plasma state, and then implanting the metal ions into a sapphire by extracting the metal ions from the plasma and accelerating the metal ions (step 1); and heat-treating the sapphire implanted with the metal plasma ions in an oxygen atmosphere or in air (step 2). According to the method of manufacturing a sapphire of the present invention, a sapphire, which can exhibit various colors, can be manufactured by implanting the ions, which can cause optical band gap changes into the sapphire, and a sapphire, which cannot be damaged by radiation and can exhibit colors uniformly, can be manufactured by conducting heat treatment under an oxygen atmosphere. Further, according to the present invention, a sapphire, which cannot be damaged by radiation and can be made to exhibit uniform colors, can be manufactured by performing the above processes repeatedly.

    • The present invention relates to an XOR logic operation apparatus using a spin torque transfer-based MTJ device. The XOR logic operation apparatus includes two parallel-connected magnetic memory cells (100, 200), and a sense amplifier (300) connected to first ends of the two magnetic memory cells. Each of the magnetic memory cells includes an MTJ device (10) and a current control circuit (50). Each magnetic memory cell includes a top electrode (11) and a bottom electrode (13) configured to allow current to flow therethrough, an insulating layer (19) configured to electrically insulate the top electrode from the bottom electrode, and a free magnetic layer (17) and a pinned magnetic layer (15) respectively formed on a top and a bottom of the insulating layer. The current control circuit controls flow of current passing between the top electrode and the bottom electrode, and changes a magnetization direction of the free magnetic layer.
