To provide a magnetoresistance effect element with a large MR ratio.SOLUTION: A magnetoresistance effect element comprises a first ferromagnetic layer, a second ferromagnetic layer, and a non-magnetic layer. The first ferromagnetic layer includes a first layer and a second layer. The first layer is arranged closer to the non-magnetic layer than the second layer. The first layer contains a heusler alloy which is at least partially crystallized. The second layer includes a ferromagnetic body which is at least partially crystallized, unlike the heusler alloy. The first layer and the second layer include a first atom added. The first atom is one selected from the group consisting of Mg, Al, Cr, Mn, Ni, Cu, Zn, Pd, Cd, In, Sn, Sb, Pt, Au, and Bi.SELECTED DRAWING: Figure 1

To provide a disk device capable of improving the degree of freedom of design.SOLUTION: A disk device according to one embodiment includes a plurality of magnetic disks, a spindle motor, a housing, a first substrate, and a first connector. The magnetic disks are arranged in an axial direction along a first rotation axis. The spindle motor rotates the magnetic disk. The housing has a first wall provided therein with a space housing the magnetic disk and the spindle motor, to which the spindle motor is attached, and a second wall projecting from the first wall and surrounding the space. The first substrate is attached to the outer surface of the second wall facing the outside of the space. The first connector is attached to the first substrate. The diameter of the magnetic disk is 80 mm or more and 100 mm or less. The maximum dimension of the housing in the axial direction is 26.2 mm or more.SELECTED DRAWING: Figure 1

The application discloses a magnetic recording device, a multi-state disk and a read-write method, and belongs to the field of magnetic storage. The magnetic recording device comprises a substrate and a magnetic recording film above the substrate. The magnetic recording film is circular and comprises three ferromagnetic layers separated by two non-magnetic intermediate layers. The easy magnetization directions of the three ferromagnetic layers are along the x, y and z directions respectively. The z direction is the vertical direction, and the x and y directions are in-plane directions and are along the radial direction and the tangential direction respectively. The multi-state disk comprises the magnetic recording device, a read head, a write head and magnetic shielding layers on both sides of the read head. The write head comprises a vertical magnetic pole and two pairs of horizontal magnetic poles, and coils wound on the magnetic poles. The read head comprises a spin current generation layer and a film layer structure (a magnetic tunnel junction, a spin valve or a Hall bar). The application can improve the storage density of the magnetic recording device, thereby greatly improving the storage density of the disk based on the magnetic recording device.
