A NEW MAGNETIC MATERIAL TECHNOLOGY THAT CAN GIVE LIFE TO ENERGY EFFICIENT
The physicists, from an international group, have recently figured out a new magnetic material as a result of a wide range of experiments. According to them, this magnet has the ability to create devices with amazing power efficiency and performance capabilities. This has given a new hope for the companies who are struggling hard to develop energy efficient machines.
The main advantage of an electromagnet over a permanent magnet is that the magnetic field can be quickly changed by controlling the amount of electric current in the winding. However, unlike a permanent magnet that needs no power, an electromagnet requires a continuous supply of current to maintain the magnetic field.
In the present world, magnetic materials such as neodymium magnets and samarium cobalt magnets are used to store almost all the types of computerized information. The negative aspect of this is that they consume a considerable amount of energy. Even though the developers have come up with some energy efficient solutions, they have not been enough to provide considerable results to computer users. The physicists who invented this sensitive magnetic predict that they will be able to develop extremely energy efficient appliances because of this strong magnet.
When a ferromagnet or ferrimagnet is sufficiently small, it acts like a single magnetic spin that is subject to Brownian motion. Its response to a magnetic field is qualitatively similar to the response of a paramagnet, but much larger.
A guaranteeing improvement is all-optical thermally induced magnetic switching (TIMS), which utilizes ultrafast laser beats to change the magnetic state of the material, equal to composing a solitary bit of information. Altogether optical exchanging there is no compelling reason to utilize magnetic fields to compose the information thus a critical lessening in force utilization might be made. Additionally, the kept laser vitality for every composed bit is much more diminutive.
Up to this point, only ferrimagnetism have shown all-optical switching properties. However, these materials are both troublesome to handle at the Nanoscale essential for mechanical gadgets and unreasonable because of their utilization of uncommon earth metals, like, Gadolinium and Terbium. However, this magnet has the ability to deliver all-optical switching properties without much hassle.
In particular, a phenomenon that appears purely electric or purely magnetic to one observer may be a mix of both to another, or more generally the relative contributions of electricity and magnetism are dependent on the frame of reference. Thus, special relativity “mixes” electricity and magnetism into a single, inseparable phenomenon called electromagnetism, analogous to how relativity “mixes” space and time into spacetime.
The exploration gained monetary backing from the EU Seventh Framework Program, and in addition the Netherlands Organization for Scientific Research (NWO) and the Foundation for Fundamental Research on Matter (FOM). With their support, the physicists are working hard to add this new material in appliances and see how it works.
