Magnetic vortex in future data storage devices, Magnetic (anti) sky is microscopic vorticity that occurs in a special class of magnetic materials.
These nanoscale objects can be used to host digital data in sequence along a magnetic strip due to their presence or absence.
A team of scientists found that skyrmions and antiskyrmions can coexist, opening up opportunities to expand their capabilities in storage devices.
With the increasing volume of digital data from more and more devices, the demand for storage capacity has increased dramatically in recent years.
Conventional storage technology is speeding up. At the same time, the ever-increasing energy consumption of hard drives (HDD) and direct access memory (RAM) is in conflict with the green energy landscape. Magnetic vortex in future data storage devices.
New devices that have higher performance are required with drastically reduced power consumption.
A promising device is a magnetic storage device for the horse racing track. It consists of nanoscopic magnetic strips (race tracks) where data is encoded in magnetic nanoscale objects, usually with their presence or absence at certain positions.
A possible nanoscale object is a magnetic (anti) skyrmion: it is a very stable magnetizing vortex with micrometers up to nanometers in size. These objects can be recorded and deleted, and mainly driven by currents, which allows them to control horse racing without moving any part.
By stacking many race tracks on top of one another to make internal three-dimensional storage devices, storage capacity can be significantly increased compared to hard drives and even hard drives. Magnetic vortex in future data storage devices.
In addition, such horse racing devices operate with a fraction of the energy consumption of conventional storage devices. It will be much faster and much more concise and reliable.
The research team at the Max Planck Institutes in Halle and Dresden and MDM found that under certain conditions, antisquirion and skyrmion can be present in the same material.
The measured monocrystalline material, Hessler’s compound.
Skyrmions and antiskyrmions are stabilized in different materials through magnetic interactions, which are directly related to the structure of the host material. Magnetic vortex in future data storage devices.
In some materials only sky fibers can be formed, whereas in other materials anti-sky fibers are preferred by this interaction.
What has so far been ignored, however, is that individual magnets in each material (“magnetic dipole”) also interact significantly with each other through their dipole-dipole interactions. Magnetic vortex in future data storage devices.
This interaction always prefers skyrmions. For this reason, “anti-germination material” can also have a sky frame (but not vice versa). It is preferred to reduce the temperature. At critical transition temperatures, two separate objects exist side by side.
In addition to its core relevance, this finding allows an expanded version of data storage in racing memory, where the sequence of bits can be encoded, for example, with the order of skyrmions (‘1’ bits) and antiskyrmions (‘0’ bits).
