Magnetic Properties of Cubic Laves Phase Transition-metal Compounds
Electronic structures of d-electrons in the cubic Laves phase transition-metal compounds are calculated in the tight-binding approximation. By making use of the calculated density-of-states curves, various magnetic properties of these compounds are calculated and compared with experiment. The magnetic properties of the intermetallic compounds with the C15-type Laves phase structure have so far ...
متن کاملMagnetic anisotropy of deposited transition metal clusters
We present results of magnetic torque calculations using the fully relativistic spin-polarized Korringa-Kohn-Rostoker approach applied to small Co and Fe clusters deposited on the Pt(111) surface. From the magnetic torque one can derive amongst others the magnetic anisotropy energy (MAE). It was found that this approach is numerically much more stable and also computationally less demanding tha...
متن کاملThe Effect of Transition Metals Incorporation on the Structural and Magnetic Properties of Magnesium Oxide Nanoparticles
Pure and doped magnesium oxide nanoparticles were successfully synthesized employing a sol-gel process. The synthesized nanoparticles were characterized by thermal differential analysis, X-ray powder diffraction, transmission electron microscopy, scanning electron microscope, energy-dispersive X-ray spectroscopy, and vibrating sample magnetometer. X-ray diffraction patterns confirmed the crysta...
متن کاملMagnetic Excitations in Transition Metal Systems
-An expression for the neutron scattering cross section based on itinerant electron theory within RPA hai been derived which incorporates the most general form of the exchange matrix consistent with crystal symmetry. Numerical results indicate a wider range of spin-wave behavior than found previously. The magnetic properties of transition metal systems are difficult to calculate because the ele...
متن کاملTemperature evolution of structural and magnetic properties of transition metal clusters
We report an extension of our tight binding molecular dynamics method @Phys. Rev. B 57, 10069 ~1998!# by incorporating the Nosé-bath and the multiple histogram approximations, so as to be applicable to cluster studies at finite temperatures in an efficient way. This generalization allows one to calculate the caloric curve for the cluster and use this to study the effect of temperature on the st...
