    Abstract: A perpendicular magnetic recording medium having a good thermal stability and a high recording density is provided. The perpendicular magnetic recording medium includes at least a first and a second perpendicular magnetic recording layer and a substrate supporting the first and the second perpendicular magnetic recording layers. The first and the second perpendicular magnetic recording layers have different physical/magnetic properties and are formed of materials that compensate the different physical/magnetic properties. The first and the second perpendicular magnetic recording layers are selected from a layer for improving perpendicular magnetic anisotropic energy (Ku), a layer for reducing the size of crystal grains, a layer for reducing the size of magnetic domains, a layer for increasing an SNR, a layer for improving signal output, a layer for reducing noise, a layer for improving the uniformity of crystal grain sizes, and a layer for improving the uniformity of magnetic domain sizes.

    Abstract: A magnetoresistive random access memory is provided. The magnetoresistive random access memory includes a first magnetic layer of which the direction of a magnetic vector is fixed, a second magnetic layer which is positioned in parallel with the first magnetic layer and of which the direction of a magnetic vector is reversible, and a non-magnetic layer interposed between the first and second magnetic layers, the second magnetic layer having an aspect ratio of 2 or less, a thickness of 5 nm or less, and a saturation magnetization of 800 emu/cm3 or less. The magnetoresistive random access memory has kink-free, magneto-resistance characteristics, thereby exhibiting high selectivity regardless of process capability.

    Abstract: Provided is a thermally stable perpendicular magnetic recording medium. The provided perpendicular magnetic recording medium includes a perpendicular magnetic recording layer between a lower layer and an upper layer, wherein a thickness of the perpendicular magnetic recording is determined by Equation 7, in the case of K>105 erg/cm3 and D > ( 30 ⁢ k B ⁢ T π ⁢ K ⁢   ⁢ A ) 1 / 2 , and determined by Equation 9, in the case of K>105 erg/cm3, n > 30 ⁢ k B ⁢ T π ⁢   ⁢ D 2 ⁢ A ⁢   ⁢ K , and ⁢   ⁢ D ≤ ( 30 ⁢ k B ⁢ T π ⁢ K ⁢   ⁢ A ) 1 / 2 . The provided perpendicular magnetic recording medium includes the perpendicular magnetic recording layer having a thermally stable thickness even when the value of K is large and an energy barrier does not follow KV. Thus, data recorded on the provided perpendicular magnetic recording medium is preserved for over 10 years.
