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…
Mott insulator phases and first-order melting in BSCCO crystals with periodic surface holes
S. Goldberg, Y. Segev, Y. Myasoedov +7
We measured the effects of periodic surface holes, created using a focused ion beam, on the phase diagram of the vortex matter in high-T_c Bi_2Sr_2CaCu_2O_{8+δ} crystals. Different…
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…
Mechanics of Individual, Isolated Vortices in a Cuprate Superconductor
Ophir M. Auslaender, Lan Luan, Eric W. J. Straver +7
Superconductors often contain quantized microscopic whirlpools of electrons, called vortices, that can be modeled as one-dimensional elastic objects. Vortices are a diverse playgro…
Multiple Changes of Order of the Vortex Melting Transition in BSCCO with Dilute Columnar Defects
Tal Verdene, Haim Beidenkopf, Yuri Myasoedov +4
A low concentration of columnar defects is reported to transform a first-order vortex lattice melting line in BSCCO crystals into alternating segments of first-order and second-ord…
Ignition and Propagation of Magnetic Avalanches in Mn-Acetate: the effect of quantum tunneling
S. McHugh, R. Jaafar, M. P. Sarachik +6
Using a wire heater to ignite magnetic avalanches in fixed magnetic field applied along the easy axis of single crystals of the molecular magnet Mn-acetate, we report fast l…
