41 Abstract Ferro convection induced by magnetic field dependent viscosity in an anisotropic porous medium using Darcy model is studied with computational methods. Galerkin method is applied. Linear stability analysis is carried out for both stationary and oscillatory modes. The critical magnetic Rayleigh number is computed for various values of the parameters which characterize the flow. It is...
We investigate the phase diagram of S=1 quantum spin systems with SU(2)-invariant interactions, at low temperatures and in three spatial dimensions. Symmetry breaking and the nature of extremal states can be studied using random loop representations. The latter confirm the occurrence of ferro- and antiferromagnetic transitions and the breaking of SU(3) invariance. And they reveal the peculiar n...

In the title compound, [FePt(C(5)H(5))(C(24)H(19)NP)Cl(2)]·0.5CH(2)Cl(2), the Pt(II) atom adopts a distorted square-planar geometry defined by one P atom and one N atom from the bidentate [2-(diphenyl-phosphino)phenyl-imino-meth-yl]ferro-cene ligand and two Cl atoms. Two disordered dichloro-methane solvent mol-ecules are each 0.25-occupied on a twofold rotation axis.

We show that by displacing two optical lattices with respect to each other, we may produce interactions similar to the ones describing ferro-magnetism in condensed matter physics. We also show that particularly simple choices of the interaction lead to spin-squeezing, which may be used to improve the sensitivity of atomic clocks. Spin-squeezing is generated even with partially, and randomly, fi...
We investigate theoretically the ground state of the FeMn binary alloy monolayer on the W(001) surface, the stability of different magnetic configurations (ferro/antiferromagnetic, disordered local moments, etc.) and estimate concentrations at which a transition occurs between different magnetic orders. The tight-binding linear muffin-tin orbital method combined with the coherent potential appr...
