Society’s increasing use of electronic devices motivates the search for new and better data storage techniques. Magnetic storage devices, such as hard disk drives, have been the mainstays for data storage over the past few decades. However, these devices, which use ferromagnetic bit orientation to store data, are fast approaching their physical limits. Replacing ferromagnets with antiferromagnets, the magnetic cousin of ferromagnets, can address this limitation, but controlling the magnetic orientation of antiferromagnetic bits is a challenge. For his Ph.D. research, Casper Schippers studied several aspects of different antiferromagnetic materials to ascertain their suitability for future data storage applications.
