Researchers have developed a new method of studying tiny magnets that could yield high-density memory based on the emerging field of spintronics.
implanting tiny “ferromagnets” onto processor chips, researchers expect
to create small electronic devices and computers that never need to
boot up. Ferromagnets are magnets made of ferrous metal such as iron, and are used in common items such as refrigerator magnets.
According to experimental physicist Chris Hammel, ferromagnets are central to incorporating memory directly into the basic logic elements at the heart of a computer.
