Wholly organic ferromagnets are a new class of materials of great potential interest, but the early examples exhibit only very weak magnetic order at very low temperatures (M. Tamura et al., Chem. Phys. Lett., 186 (1991) 401). In these circumstances, muon spin rotation (μSR) is among ...
Noncollinear spin textures in low-dimensional magnetic systems have been studied for decades because of their extraordinary properties and promising applications derived from the chirality and topological nature. However, material realizations of topolog
Mssbauer studies of topologically frustrated ZnCr2xGa22xO4 system (0.6 x 1) are performed. Almost all the spectra consist of a superposition of a paramagnetic doublet and an enlarged magnetic hyperfine pattern. Two models are used to fit the spectra, a static hyperfine field distribution method...
The spin transitions of Fe2+ and Fe3+ cause an abrupt reduction of c-axis at 8.5 GPa and 17 GPa, respectively while these transitions affect a-axis and b-axis only slightly. As shown in Figure S1(b), layers of Fe2+ and Fe3+ alternate with a cation ordering of Fe2+- Fe3+...
An external field can only flip the magnetic moment of the layer with smaller coercivity so that the sf-MTJ can switch between the PC and APC with different conductivities [27]. The sf-MTJs have the potential to work in a small field, above room temperature and to possess larger ...
microstructure [1], with that of LaSr2Cr2SbO9, which has a partially–ordered distribution of d3:Cr3+ and d10:Sb5+ cations and a relatively simple microstructure [2]; the former shows many of the characteristics of a spin glass below 35 K whereas the latter is ferrimagnetic below ...
A spin of the molecule was detected by a clear Kondo resonance in dI/dV spectra of the tunnelling current of the STM. The Kondo effect originates from an unpaired spin in a π-orbital of the phthalocyaninato (Pc) ligands rather than from the local magnetic moment of the metal ion. We...
applying a magnetic field with aB//Econfiguration can significantly enhance the polarization from 33.3 μC/m2at 0 T to 84.4 μC/m2at 6 T (Fig.2e). However, in theB⊥Econfiguration, the spin-induced polarization is suppressed to 10.7 μC/m2atB = 3 T, and only 4.51 μ...
where the sum 𝑖=1⋯𝑁i=1⋯N is over all N independent energy eigenstates (including magnetic substates), the sum ∑Ei∑Ei is over energy levels only, and 𝛽β = 1/k𝑏bT. In practice, we will employ the usual set of 𝑧̂z^-polarized magnetic basis states. While the ...
The XMCD method owes its broad practical applicability to the discovery of the so-called sum rules regarding the orbital [43] and the spin magnetic moment [44], which relate the measured helicity-dependent absorption difference to the local orbital and spin magnetic moments of the absorbing atom...
