Conventional hard disk drives (HDD) use the in-plane magnetic recording technology. The maximum density of stored information is only 160 Gb/in2. Since the first generation of perpendicular magnetic recording HDD was realized in 2006, the high-density magnetic recording was established that is 500 Gb/in2 in 2010. It was predicted that the density of information can achieve up to 1.5 Tb/in2 before the perpendicular magnetic recording is replaced by more advanced technologies. The PdCo alloy is a good candidate for the perpendicular magnetic recording HDD. Therefore, we studied the perpendicular magnetic anisotropy of the PdCo alloy by using the density functional theory calculations. Electronic properties were analyzed to clarify the magnetic anisotropy of this alloy.
