Researchers celebrate 20th anniversary of IBM’s invention of Spin Torque MRAM by demonstrating scalability for the next decade

“A new mechanism is proposed for exciting the magnetic state of a ferromagnet.” Twenty years ago, these words were written by IBM scientist John Slonczewski in his seminal paper entitled “Current-driven excitation of magnetic multilayers” in the Journal of Magnetism and Magnetic Materials. Today, they are helping scientists overcome several technical hurdles in the development […]

IBM Celebrates 20th Anniversary of Moving Atoms

On September 28, 1989, Don Eigler became the first person in history to move and control an individual atom. Shortly thereafter, with the help of a custom-built microscope, he and his team spelled out the letters I-B-M using individual atoms, signaling a quantum leap forward in the field of nanotechnology. Eigler built his scanning tunneling […]
