Magnetic Materials

A new spin on energy-efficient electronics

Researchers are harnessing the power of Argonne’s Advanced Photon Source to test new materials for use in spintronics. This emerging field uses electron spin instead of charge, allowing manufacturers to make smaller and more efficient electronic devices.

A New Twist on Controlling Magnetic Properties

Computer storage devices often use magnetic materials printed on very thin films. In this study, researchers rotated cobalt-iron alloy thin films relative to an applied magnetic field. Unexpectedly, depending on the rotation angle, a sizeable change – up to 400% – was seen in how well the material holds on to energy.
