SAW interdigitated transducers as topological mechanical metamaterial
S. McHugh
A lattice model is developed to describe the mechanical displacement of and current through each electrode of a surface acoustic wave (SAW) interdigitated tranducer (IDT). Each ele…
Magnetic Avalanches in Molecular Magnets
Myriam P. Sarachik
The reversal of the magnetization of crystals of molecular magnets that have a large spin and high anisotropy barrier generally proceeds below the blocking temperature by quantum t…
Magnetic Avalanches in Molecular Nanomagnets
M. P. Sarachik, S. McHugh
The magnetization of the prototypical molecular magnet Mn12-acetate exhibits a series of sharp steps at low temperatures due to quantum tunneling at specific resonant values of mag…
Magnetic avalanches of minor fast-relaxing species of Mn12-acetate
S. McHugh, R. Jaafar, M. P. Sarachik +5
Using micron-sized thermometers and Hall bars, we report time-resolved studies of the local temperature and local magnetization for two types of magnetic avalanches (abrupt spin re…
Tuning Magnetic Avalanches in Mn12-ac
S. McHugh, Bo Wen, Xiang Ma +5
Using micron-sized Hall sensor arrays to obtain time-resolved measurements of the local magnetization, we report a systematic study in the molecular magnet Mn-acetate of mag…
Experimental determination of the dipolar field in Mn12-acetate
S. McHugh, R. Jaafar, M. P. Sarachik +5
Crystals of the molecular magnet Mn12-acetate are known to contain a small fraction of low- symmetry (minor) species with a small anisotropy barrier against spin reversal. The lowe…
