摘要:Magnetic properties of the 3$d$(Fe)–4$f$(RE) intermetallides are calculated by introduction of both the many-electron operator spinors (MEOS) and the chemical-bonds’ fluctuations as MEOS Fourier images. Dependences of both the critical temperature $T_{\textrm{c}}$ and the co...

摘要:Magnetoelectric effects in rare-earth metals (REM) are ‘giant’ due to large spin ($\textbf{S}_{\textbf{r}}$), orbital ($\textbf{L}_{\textbf{r}}$), and angle ($\textbf{J}_{\textbf{r}}$) moments of rare-earth ions (REI) in sites $\textbf{r}$. Unitary description of them is pos...

摘要:Metallic U is calculated by means of the method of many-electron operator spinors. Atomic phase diagram is accompanied by dividing of 5$f$-shell on $e_{\textrm{g}}$ (5$f^1$) and $t_{2\textrm{g}}$ (5$f^2$) subshells. Destabilization of U ion electronic structure is connected ...

摘要:Magnetoelectric properties of Fe-based amorphous metals (AM) are calculated within both the cluster ($K_j$) model and the many-electron operator spinors representation. AM are modified by the chemical-bond fluctuations (CBF) and microdiffusion. The wave function of Fe ion co...

摘要:The symmetry of rare-earth metals (REM) and f.c.c.-Ce ‘paradox’ are calculated by means of the method of many-electron operator spinors (MEOS). Spin and orbital MEOS factors with [0001] axis of quantization of the angular moment $J$ are responsible for hexagonal deformation ...

摘要:The bulk and linear ordering of A$_{1-c}$B$_{c}$ alloy ($c << 1$) is calculated by the method of the many-electron operator spinors (MEOS). Nominal value of order parameter $P(c)$ is limited by competition of covalent A—B and A—A bonds $\Gamma$ and the Hubbard repulsion $U$.

摘要:The quantum theory of Ce alloys is constructed by the method of the many-electron operator spinors (MEOS). Ce$_{1-c}$Al$_{c}$ alloys show the shape memory effect (SME) as an atomic ordering (AO) transition. AO hysteresis is calculated by introduction of AO domains and their walls...

摘要:The quantum-statistical theory of amorphous metal (AM) is developed by an example of Fe—B. As supposed, the short-range order clusters ($K_{j}$) of high-spin (HS) Fe ions are separated by holes ($h_{ij}$) of low-spin (LS) Fe ions covalently bonded with B$^{+}$ cations. Wave-...
