    Extractions: Magnetism of High Temperature Superconductors The discovery of superconductivity in the doped copper oxides has stimulated the study of the magnetism in these materials, both because of its intrinsic interest and its connection to high temperature superconductivity. The undoped parent compounds are antiferromagnetic (AF) insulators. The long-range AF order is rapidly destroyed with doping, and upon further doping the system becomes superconducting, while short-range AF correlations still persist. The copper oxide materials are strongly anisotropic, both with respect to their transport and magnetic properties. It is widely believed that the CuO planes are responsible for the properties of those materials. Doping introduces holes which are the charge carriers in the AF square lattice of the CuO planes. The simplest model that seems to contain the physics of the CuO planes is the t-J model, which describes holes moving in a Heisenberg spin system. In this system the holes are strongly coupled to the spin array, the motion of holes generating spin fluctuations. A striking feature of the copper oxides is the strong sensitivity of their magnetic properties to hole concentration. Our work has been concerned with the understanding of this aspect. We have studied the effects of doping on a set of magnetic properties, namely, spin excitations, susceptibility, and staggered magnetization, within the t-J model. Quantum many-particle techniques were used to calculate the renormalization of the magnetic properties induced by the hole-magnon interaction. We found that those properties strongly depend on doping due to the hole-magnon interaction generated by hole motion, our results showing good agreement with experimental data on the copper oxide high temperature superconductors.

    Extractions: Finite-temperature magnetism of transition metals: Magneto-optical properties of MnBi: Magnon-phonon interactions in Iron: First-principle studies of magnon-phonon interactions are carried out in bcc and fcc iron in the adiabatic approximation. It is shown that the phonons have minor effect on magnons in bcc Fe and thus the lattice vibrations make a small contribution to the Curie temperature. Fcc Fe is unstable against magnon excitations but the phonons seem to reduce this instability. The magnon-phonon interactions are analyzed in terms of the pair-exchange interaction variations as functions of the interatomic distances. The obtained dependencies can be used for analysis of distorted and disordered systems. Permanent-Magnet Materials: Potential applications of permanent magnets in bearings, sensors, motors drive the very active research in this area. The understanding of basic properties of permanent magnet materials (which are basically iron and cobalt rich rare-earth(RE) transition metal compounds)is essential to know the limits and potentials of the materials. We participate in the ongoing research supported by DOE, DARPA and AFOSR. Our objective is the study of the basic properties of newly synthesized materials (like RE5Fe17, RE3(Fe,Co)29), series of well-known compounds trying to improve their properties by doping, and considering hybrid(so-called exchange spring) magnet structures.
