Evaluation of Machine Learning Reconstruction Techniques for Accelerated Brain MRI Scans
Jonathan I. Mandel, Shivaprakash Hiremath, Hedyeh Keshtgar +2
This retrospective-prospective study evaluated whether a deep learning-based MRI reconstruction algorithm can preserve diagnostic quality in brain MRI scans accelerated up to fourf…
Damping of magnetization dynamics by phonon pumping
Simon Streib, Hedyeh Keshtgar, Gerrit E. W. Bauer
We theoretically investigate pumping of phonons by the dynamics of a magnetic film into a non-magnetic contact. The enhanced damping due to the loss of energy and angular momentum…
Magnetomechanical coupling and ferromagnetic resonance in magnetic nanoparticles
Hedyeh Keshtgar, Simon Streib, Akashdeep Kamra +2
We address the theory of the coupled lattice and magnetization dynamics of freely suspended single-domain nanoparticles. Magnetic anisotropy generates low-frequency satellite peaks…
Coherent elastic excitation of spin waves
Akashdeep Kamra, Hedyeh Keshtgar, Peng Yan +1
We model the injection of elastic waves into a ferromagnetic film (F) by a non-magnetic transducer (N). We compare the configurations in which the magnetization is normal and paral…
Acoustic parametric pumping of spin waves
Hedyeh Keshtgar, Malek Zareyan, Gerrit E. W. Bauer
Recent experiments demonstrated generation of spin currents by ultrasound. We can understand this acoustically induced spin pumping in terms of the coupling between magnetization a…
