Broadband spectroscopy of thermodynamic magnetization fluctuations through a ferromagnetic spin-reorientation transition
A. L. Balk, F. Li, I. Gilbert +3
We use scanning optical magnetometry to study the broadband frequency spectra of spontaneous magnetization fluctuations, or "magnetization noise", in an archetypal ferromagnetic fi…
Bubble Magnetometry of Nanoparticle Heterogeneity and Interaction
A. L. Balk, I. Gilbert, R. Ivkov +2
Bubbles have a rich history as transducers in particle-physics experiments. In a solid-state analogue, we use bubble domains in nanomagnetic films to measure magnetic nanoparticles…
Electric-field Induced Reversible Switching of the Magnetic Easy-axis in Co/BiFeO3/SrRuO3/SrTiO3 Heterostructures
T. R. Gao, X. H. Zhang, W. Ratcliff +8
Electric-field (E-field) control of magnetism enabled by multiferroics has the potential to revolutionize the landscape of present memory devices plagued with high energy dissipati…
Simultaneous control of the Dzyaloshinskii-Moriya interaction and magnetic anisotropy in nanomagnetic trilayers
Andrew L. Balk, Kyoung-Whan Kim, Daniel T. Pierce +3
Magneto-optical Kerr effect (MOKE) microscopy measurements of magnetic bubble domains demonstrate that Ar+ irradiation around 100 eV can tune the Dzyaloshinskii-Moriya interaction…
Interfacial Coupling in Multiferroic-Ferromagnet Heterostructures
M. Trassin, J. D. Clarkson, S. R. Bowden +6
We report local probe investigations of the magnetic interaction between BiFeO3 films and a ferromagnetic Co0.9Fe0.1 layer. Within the constraints of intralayer exchange coupling i…
Anisotropy of Magnetization Reversal and Magnetoresistance in Square Arrays of Permalloy Nano-Rings
A. V. Goncharov, A. A. Zhukov, V. V. Metlushko +8
Magnetization reversal mechanisms and impact of magnetization direction are studied in square arrays of interconnected circular permalloy nanorings using MOKE, local imaging, numer…
