Scientists from Switzerland have developed just made writing and accessing data on storage systems like hard drives much simpler.
The development of a new perovskite material with distinct magnetic properties can now be used to build next-generation hard drives with higher density and efficiency to store generation of more and more data.
For this, materials whose magnetic properties can be quickly and easily manipulated in order to write and access data on them, are needed.
Scientists from Ecole Polytechnique Federale de Lausanne (EPFL) have developed a perovskite material - a calcium titanium oxide mineral composed of calcium titanate - whose magnetic order can be rapidly changed without disrupting it due to heating.
Magnetism in material arises from the interactions of localised and moving electrons of the material. By easily modifying magnetic properties, it could of an enormous advantage in many applications such as magnetic data storage, some of the advantages of which are long-term stability, high data density, non-volatile operation and re-writability - with the speed of optical writing and reading.
