What is a magnetic semiconductor?
Magnetic semiconductor is a type of substance that is semiconducting and ferro-magnetic. The magnetic semiconductor materials produce the attraction of a similar force of a normal magnet. Most ferromagnets such as iron are very electrically conductive; However, the magnetic semiconductor is neither completely conductive nor purely resistant. Thanks to this unique combination of conductive and magnetic attributes, the material is useful in newer types of computers.
The study of magnetic semiconductors began in the 70s and 80s. During this period, scientists observed several unknown electrical behavior in metal and semiconductors. The observation of the phenomenon of the magnetic semiconductor led to the theory of "spintronics". This developing area of computer science makes it possible to control the direction of the charge and the rotation of the electron. While a traditional semiconductor, such as a transistor, can only control electrical charges, the magnetic semiconductor provides more precismanipulation with the status of electron.
Computers usually use semiconductors and electromagnets for separate functions. For theRacing and calculations are used semicondurative material such as silicon chips. Electromagnetic materials are often used to store data, for example on hard drive disks. However, the transfer of data from a semiconductive processor to magnetic storage is not immediate. This time -consuming data transmission is commonly observed when the computer is "introduction" and loads the operating system.
using spinTronics would eliminate the magnetic semiconductor memory and dramatically increase the speed of computers. This type of material combines magnetic storage and semiconductor processing functions and allows you to handle and store information on the same chip. The magnetic semiconductor computer can be immediately introduced because there is no need to carry out data from a separate storage device.
The temperature is one of the primary challenges in building magnetic semiconductor devices. Materials usually show magnetic and semiconducting CHidding at very low temperatures; This is a significant problem because computers must be able to work at room temperatures to be practical. Many scientists experiment with a combination of different substances to create a material that is ferro-magnetic and semiconductor at nominal temperatures.
These materials have other possible applications in addition to computer devices. Magnetic semiconductors can be useful in creating very accurate sensors. New sensors can be able to detect and store important information on one unit. The development of this technology can also be used for powerful and accurate lasers that can be useful in medicine.
