Figure 1: Two plots showing the results of using ultrasound to probe a magnetic material known as an antiferromagnet at temperatures of 4.2 kelvin (left) and 10 ...
Computer engineers are bringing the minimalist approach to medical care and computing by coupling USB-based ultrasound probe technology with a smartphone, enabling a compact, mobile computational ...
Today’s data-storage devices mostly rely on ferromagnets—magnetic materials such as iron, nickel and cobalt in which all the magnetic fields of the atoms are aligned with each other. But another class ...
