Reserchers from Keio University and Oxford University have successfully generated and detected quantum entanglement between electron spin and nuclear spin in phosphorus impurities added to silicon. This is the world's first successful generation and detection of entanglement, which is essential for quantum computing, in silicon, which is used as a semiconductor in all computers. This accomplishment constitutes a major breakthrough toward the achievement of quantum computers.
Here's a nice introduction-to-spintronics video from the Tanaka Laboratory at the University of Tokyo. They explain what is Spintronics, and how it can be applied to memory devices (hard disks and MRAM) and information processing with low power consumption:
A short video about the University of Tokyo's Ohtani Laboratory spintronics research, which is focused on spin-polarized current and pure spin current:
Here's a nice video explaining Tsukuba University's Spin-Filters research:
A group led by Professor Hideo Ohno in the Laboratory of Nanoelectronics and Spintronics, at Tohoku University is working to develop new integrated circuits using spintronics. The ICs store data in nonvolatile memory using magnetism (MRAM), so their standby power can be made zero. This memory utilizes the tunnel magneto-resistance effect.

Prof. Albert Fert (who won the Nobel prize in 2007 for GMR) talks about GMR and Spintronics:
David Awschalom of the University of California brings us a good introduction to Spintronics:
Professor Kohei Itoh of Keio University gives a lecture on Silicon Quantum Information Processing. The lecture includes topics such as Elements of quantum computation, Nuclear spin coherence in Silicon and Silicon spintronics.
