  • Strong vortex core pinning and Barkhausen-free Magnetization Response in thin Permalloy disks induced by implantation of 1 × 104 Ga+ ions
    Journal of Applied Physics, 2014
    Co-Authors: Fatemeh Fani Sani, Joseph E. Losby, Zhu Diao, L. C. Parsons, Jacob A. J. Burgess, D. Vick, Wayne K. Hiebert, Mark R. Freeman
    Abstract:

    Artificial vortex core pinning sites are induced in thin Permalloy disks by point exposure to as few as 10 000 ions from a focused Ga+ beam. These pinning sites yield a first-order change in the Magnetization Response of the disk. A single site can keep the vortex core pinned over an applied field range comparable to the vortex annihilation field of the unaltered disk. Several widely separated sites can work together to keep the core pinned in one place, while the Barkhausen effect is eliminated from the Magnetization curve over a range approaching the saturation moment of the disk.

  • Nanomechanical AC susceptometry of an individual mesoscopic ferrimagnet
    Solid State Communications, 2014
    Co-Authors: Joseph Losby, Fatemeh Fani Sani, Zhu Diao, Jacob A. J. Burgess, Wayne K. Hiebert, D. T. Grandmont, M. Belov, Mark R. Freeman
    Abstract:

    A novel method for simultaneous detection of both DC and time-dependent magnetic signatures in individual mesoscopic structures has emerged from early studies in spin mechanics. Multifrequency nanomechanical detection of AC susceptibility and its harmonics highlights reversible nonlinearities in the Magnetization Response of a single yttrium iron garnet (YIG) element, separating them from hysteretic jumps in the DC Magnetization
