The one-dimensional Tasaki-Hubbard model belongs to the class of flat-band ferromagnets. By introducing an infinitesimally small external magnetic field, we examine the properties of the model in the paramagnetic regime. We compare and contrast them to the properties of the conventional Curie paramagnet.

The paper presents a new polymeric polyoxomolybdate cluster with infinite octamolybdate chains cross-linked by iron (II) centers. The layer-type substance contains sodium cations sandwiched between the [Fe(H2O)4Mo8O27]∞ layers. The structure was determined by single crystal X-ray diffraction analysis. Magnetic properties, due to the presence of paramagnetic iron (II) centers, are presented and discussed.
