Spintronics is an emerging technology which makes use of the influence of charge, spin and magnetic moment of the electron for electrical conduction in an electronic device. The market for devices employing the spintronics technology is on rise at a global scale. The concept of exploiting the spinning attributes of electron is projected to open up a whole new range of applications in electronic such as in MRAM devices, read heads of hard discs, sensors, magnetic tunnel transistors, electric vehicles and so on. Apart from its powerful applications in mass storage, spintronics has potential to provide opportunities in the emerging fields such as in nano electronic technology. The spintronics technology, thus, has a lot of future opportunities and prospects to grow and this is forecast to fuel the spintronics market in the years to come. However, the spintronics market faces a number of challenges for the technology to come into action, like spin dynamics and spin pumping phenomena, deve...
