These theories are applicable to electron-electron interaction only when the fast relaxing magnetic ion does not have a crystal field splitting (e.g., a low-spin Fe3+ ion). There are two different aspects of the relaxation problem. One deals with the evaluation of the spin-spin interaction ...
In addition, the SMR has also been revealed sensitive to the thickness of MCVA in the MCVA/Pt heterostructure. 2. Experiments Mn-Co-V-Al films with thicknesses from 7 to 24 nm are grown on MgO (100) substrates at 600 °C by DC co-sputtering of Mn2VAl and Co targets, with a...
More specifically, all-optical switching (AOS) of magnetic materials, whereby the magnetization can be reversed on a picosecond timescale using only femtosecond (fs) laser pulses, has striking potential. First discovered around a decade ago2, it has since been shown that two mechanisms can be ...
We have studied the paramagnetic resonance signal (PRS, Δm=+1) of the 3d5 spin of Mn2+ in Cd1-xMnxTe epilayers and, less extensively, in a quantum-well structure by means of Raman spectroscopy in an external magnetic field of 6 T at low temperatures. The exciting laser or the scattere...
the XMCD signal appears. This suggests the appearance of a net magnetic moment. At 80 K, the film displays a further enhanced XMCD signal, only at MnL3,2-edges. As XMCD contains both net spin (mspin) and orbital (morb) magnetic moments, one can estimate the total magnetic moment,mto...
cell. The magnetic moments of Fe2 and Mn1 and those of Fe1 and Mn2 point in opposite directions. Our calculation [17] yields the magnetic moments as m Fe 1:4 B and m Mn 1:9 B . When a current passes through an antiferromagnetic material, the current-induced nonequilibrium...
The experimental demonstration of the SPE has become possible only recently based on the idea that spin currents passing through a magnetic texture would heat one end and cool down the other, thereby creating a thermal gradient3,4. At the same time, ultrafast manipulation and control of spin ...
However, the calculations clearly show that the layered magnetic structures are considerably lower in energy as compared to a homogeneous magnetic ground state, e.g. 9.3 meV/f.u. The ordering of the tetrahedral chains considered only weakly influences the magnetic ground state (See Supplementary ...
Mn(1) has a smaller magnetic moment (3.07 µB) than Mn(2) (3.91 µB) implying that Mn(1) corresponds to Mn3+ and Mn(2) to Mn2+, both in high-spin states. The electronic structure indicates that it is an indirect band-gap semiconductor with a band gap of 0.88 eV, in ...
