Cooling phonons with phonons: Acoustic reservoir engineering with silicon-vacancy centers in diamond

K. V. Kepesidis, M.-A. Lemonde, A. Norambuena, J. R. Maze, and P. Rabl

Phys. Rev. B 94, 214115 (2016) - Published 29 December, 2016

The authors propose a new method for realizing mechanical ground-state cooling that could generate quantum entanglement at convenient temperatures (1 K). They consider a diamond beam bending above a magnetic tip (the beam is clamped at one end and free to move at the other). Near the oscillating end, they insert a lattice defect, specifically a silicon-vacancy center. As the beam bends, the defect experiences a varying magnetic field which may flip its spin by absorbing mechanical energy from the low-frequency flexural motion of the beam. At the same time, the center is coupled to high-frequency compression modes, which locally distort the surrounding lattice and lead to a fast relaxation of the center’s electronic states. By stimulating the defect with microwave fields, these two coupling mechanisms can be connected and an energy flow from the bending motion into the high-frequency phonon reservoir is induced. According to predictions made here, the mechanical temperature of the beam – how much it bends – can then be tuned via optimizing these alternating absorption and reemission processes in the same way the temperature of atoms can be controlled with light.

Time-resolved studies of the spin-transfer reversal mechanism in perpendicularly magnetized magnetic tunnel junctions

Christian Hahn, Georg Wolf, Bartek Kardasz, Steve Watts, Mustafa Pinarbasi, and Andrew D. Kent

Phys. Rev. B 94, 214432 (2016) - Published 27 December, 2016

Miniaturized magnetic tunnel junctions enable single-shot time-resolved studies of magnetization reversal driven by spin currents that can test basic physical models, particularly as recent technological advances enable the study of sub-100 nm diameter junctions. The junctions consist of two magnetic layers with uniaxial magnetic anisotropy separated by a thin insulating layer that enables electron tunneling and thus transfer of spin-angular momentum in the tunneling process. One magnetic layer is free to reverse in response to the spin current while the other is fixed. Pulsed current measurements show the stochastic nature of the reversal process on nanosecond time scales and provide evidence for nonuniform magnetization reversal processes in junctions that are larger than 50 nm in diameter.

Hyperfine fields in the BaFe2As2 family and their relation to the magnetic moment

Gerald Derondeau, Ján Minár, and Hubert Ebert

Phys. Rev. B 94, 214508 (2016) - Published 12 December, 2016

The hyperfine field Bhf and the magnetic properties of the BaFe2As2 family are studied using the fully relativistic Dirac formalism for different types of substitution. Relativistic contributions were found to have a significantly stronger impact for the iron pnictides when compared to bulk Fe. Based on the calculations here and the measured hyperfine field from 57Fe Mössbauer spectroscopy for undoped BaFe2As2, we can estimate a magnetic moment of roughly 0.7–1.0 μB, which is more consistent with neutron diffraction reporting 0.87 μB. This solves the longstanding puzzle of different reports for the magnetic moment of BaFe2As2 based on either 57Fe Mössbauer spectroscopy or neutron diffraction. However, for substituted iron pnictides, the behavior of Bhf with the concentration x is clearly unpredictable and might lead to wrong conclusions. Thus, relating the hyperfine fields Bhf of Fe obtained via 57Fe Mössbauer spectroscopy to the magnetic moments is not sensible for substituted iron pnictides.
