New hard drives consume significantly less energy!
Swiss researchers have developed a material that could revolutionize data storage.
Their material modified by shock treatment can store data with significantly lower energy consumption.
And heat is also significantly less.
Materials from the class of the so-called Magnetoelectric Multiferroics are considered to be the data store of the future.
They have a larger capacity than the material used so far and above all: the energy required to store data, is far less.
They have only one disadvantage: Their outstanding performance develop only at very low temperatures.Usually minus 200°C.
In order to produce these, more than icy temperatures,much more energy is needed than the ones that are saved in writing.
Electrical instead of magnetic fields
Until now aniway. Researchers at the Swiss Paul Scherrer Institute (PSI) have now developed a Multifunctional,that works at room temperature.
Now the use as a hard disk is no longer in the way. The energy-saving effect is due to a peculiar physical property of the material in which the magnetic and electric properties are coupled together.
The magnetization of the tiny points on which bits are stored or erased, is possible with electrical fields,whose generation consumes less energy than those of magnetic fields.
If any electric field is applied to magneto-electric Multiferroids, this affects the electrical properties of the material”,explains Marisa Medarde , leader of the new study.
“The magneto-electric coupling,provides a change in the magnetic properties.”
The savings are even greater, because the lower energy consumption results in less heat.
This must be removed in order to protect the electronics from overheating and thus from the destruction.
The need for cooling is thus reduced,which reduces the power consumption once more. Since many billion of kilowatt hours of energy are consumed in the cloud computing per year, savings in this área are of great importance.
Flash rapidly cooled by 1200 ° C
The PSI researchers have achieved their goal by changing the chemical composition of the material and using a special manufacturing process. The data store of the future consists of a special iron oxide, yttrium, barium and copper. The chemical formula is YBaCuFeO5.
The material is heated to a temperature of about 1000 ° C, and then sudden on cooled minus 200 ° C.
At high temperatures, the atoms are sorted in such a way that the desired electromagnetic function is established. “The rapid cooling then freezes then freezes this arrangement”, says Medarde.
And it is preserved when the material reaches room temperature.
The material is closely related to the first high-temperature superconductors, discovered in 1987. Which lacked only the iron atom.
With a very diferente idea a Dresdner company start-up wants to go into the future .
Especially the heat of servers wants to use the company,thereby to heat family homes.
