Engineered Spatial Inversion Symmetry Breaking In An Oxide Heterostructure Built From Isosymmetric Room-Temperature Magnetically Ordered Components
An investigation into the feasibility of myoglobin-based single-electron transistors
Myoglobin single-electron transistors were investigated using nanometer- gap
platinum electrodes fabricated by electromigration at cryogenic temperatures.
Apomyoglobin (myoglobin without heme group) was used as a reference. The
results suggest single electron transport is mediated by resonant tunneling
with the electronic and vibrational levels of the heme group in a single
protein. They also represent a proof-of-principle that proteins with redox
centers across nanometer-gap electrodes can be utilized to fabricate
single-electron transistors. The protein orientation and conformation may
significantly affect the conductance of these devices. Future improvements in
device reproducibility and yield will require control of these factors
Antiferromagnetic spin Seebeck Effect
We report on the observation of the spin Seebeck effect in antiferromagnetic
MnF. A device scale on-chip heater is deposited on a bilayer of Pt (4
nm)/MnF (110) (30 nm) grown by molecular beam epitaxy on a MgF (110)
substrate. Using Pt as a spin detector layer it is possible to measure
thermally generated spin current from MnF through the inverse spin Hall
effect. The low temperature (2 - 80 K) and high magnetic field (up to 140 kOe)
regime is explored. A clear spin flop transition corresponding to the sudden
rotation of antiferromagnetic spins out of the easy axis is observed in the
spin Seebeck signal when large magnetic fields (>9 T) are applied parallel the
easy axis of the MnF thin film. When magnetic field is applied
perpendicular to the easy axis, the spin flop transition is absent, as
expected
Ferrimagnetism of dilute Ising antiferromagnets
It is shown that nearest-neighbor antiferromagnetic interactions of identical
Ising spins on imbalanced bipartite lattice and imbalanced bipartite
hierarchical fractal result in ferrimagnetic order instead of antiferromagnetic
one. On some crystal lattices dilute Ising antiferromagnets may also become
ferrimagnets due to the imbalanced nature of the magnetic percolation cluster
when it coexists with the percolation cluster of vacancies. As evidenced by the
existing experiments on , such ferrimagnetism is inherent
property of bcc lattice so thermodynamics of these compounds at low can be
similar to that of antiferromagnet on imbalanced hierarchical fractal.Comment: 6 pages, 4 figure
