We present a theory for the ab-initio computation of NMR chemical shifts (σ) in condensed matter systems, using periodic boundary conditions. Our approach can be applied to periodic systems such as crystals, surfaces, or polymers and, with a super-cell technique, to non-periodic systems such as amorphous materials, liquids, or solids with defects. We have computed the hydrogen σ for a set of fr...

Fe-rich Fe-B amorphous metals exhibit approximately collinear magnetic structure. When a certain amount of Fe atoms are replaced with Mn, the magnetic structure of the alloys is found to become non-collinear. We performed electronic structure calculations using the locally selfconsistent multiple scattering (LSMS) method for supercell samples generated by ab initio molecular dynamics simulation...

The effects of different ribbon widths on the magnetic properties of an amorphous alloy were studied. DSC, TGA, XRD, VSM, SEM and ER techniques were used. For SA1 alloy, the sample during primary crystallization for the 142mm and 213mm width ribbons are quite similar; however the magnetic properties and morphologies are significantly different. Finally, the measurements of a three-phase 2MVA am...

This is well known that amorphous state is metastable. Metastability of amorphous or glassy metal alloys offers the possibility of phase separation diffusion of various species and structural relaxation even though the alloys remains amorphous when they are annealed at temperature well below the crystallization temperature. All these changes have effect on the intrinsic magnetic properties such...

Recently, two-dimensional materials have been extensively studied. Due to the reduced dielectric screening and confinement of electrons in two dimensions, these materials show dramatically different electronic and optical properties from their bulk counterparts. So far, studies on twodimensional materials have mainly focused on crystalline materials. Here we report studies of atomically thin am...

The paper presents operational characteristics of a small induction motor with the stator core made of amorphous laminations, supplied from mains or frequency inverter at 100 and 200 Hz. Calculations were performed using field-circuit and equivalent circuit approaches taking account of non-linearity and additional losses both in the core and in the windings. Data for mechanical losses, magnetis...
