Razvijen je novi uređaj za pohranu podataka temeljen na interferenciji spinskih valova. Podaci se pohranjuju kao magnetski bitovi, a čitaju kao holografske slike. Budući da su valne duljine spinskih valova znatno kraće od svjetlosnih, gustoća pohrane podataka ima daleko veći potencijal od optičkih holograma..
Gustoća pohrane podataka ograničena je valnom duljinom koja je kod optičkih holograma reda veličine 500 nm, a kod spinskih valova približno 10 nm. Nova memorija opisana je kao vijest:

Magnonic Holographic Memory
Holography is a technique based on the wave nature of light which allows us to utilize wave interference between the object beam and the coherent background. Holography is usually associated with images being made from light, however, this is only a narrow field of holography. The first holograms were designed for use with electron microscopes and it was not until a decade later with the advent of the laser that optical holographic images were popularized. Multiple other fields have had major contributions made by using wave interference to produce holograms, including acoustic holograms used in seismic applications, and microwave holography used in radar systems. Holography has been also recognized as a future data storing technology with unprecedented data storage capacity and ability to write and read a large number of data in a highly parallel manner. Here, we present a magnonic holographic memory device exploiting spin wave interference.
