In addition, Jpyz ∼ 1 K regardless of X, and D = 8 K for NiCl2(pyz)2, whereas D ∼ 0 for X = Br, I, and NCS based on ESR and heat capacity.

    Detailed analysis of the 1H NMR spectra of paramagnetic 10-coordinated lanthanide(III) complexes, performed with the aid of density functional theory calculations, allowed a reliable separation of the contact and pseudocontact contributions to the observed paramagnetic shifts. Analysis of the pseudocontact shifts reveals magnetic anisotropies that do not follow the trends predicted by the theory developed by Bleaney.

    In view of a wide perspective of 3d–4f complexes in single-molecule magnetism, here we propose an explanation of the magnetic behavior of the two thiacalix[4]arene tetranuclear heterometallic complexes MnII2GdIII2 and CoII2EuIII2. The energy pattern of ...

    We model the magnetic behavior of the thiacalix[4]arene complexes MnII2GdIII2 (I) and CoII2EuIII2 (II). The nonmonotonic dependence of χT versus T for I (exhibiting a rotational band of spin excitations) is attributed to the competitive ferromagnetic Mn−Gd and antiferromagnetic Mn−Mn interactions. Complex II exhibits strong uniaxial anisotropy of the CoII ions and isotropic exchange in the CoII2 pair. The dominating anisotropic contribution with an easy plane of magnetization in II is described by an anisotropic effective spin-1/2 Hamiltonian.

    High-quality single crystals of multiferroic Pb2MnWO6 were successfully grown. We observe an uncommon structural transition from cubic Fm3̅m to orthorhombic Pn21a near 460 K, which we analyze and describe in detail. We show that an uncompensated antidipole order exists below 460 K, which yields a ferrielectric response of Pb2MnWO6. Magnetometry and first-principles calculations evidence a low-temperature antiferromagnetic state, with significant magnetic frustration, due to the lattice distortions and competing interaction between the Mn cations.
