I am Hari Srinvas Goripati. It’s a great pleasure to be a contributor on this blog. I am PhD student in Materials science, university of Tsukuba, Japan. But, I do all my thesis work at National Institute for Materials Science (NIMS) located in the same city and am working in the field of spintronics with a focus on Giant Magnetoresistance (GMR). To define what spintronics is, unlike in normal electronics, here the spin degree of freedom of an electron is exploited in addition to its charge in making the devices. Here is a link to spintronics on wiki. Even though I am new two blogging community, hope you will enjoy my future posts on this subject.
