چکیده
Solid solution between nonmagnetic narrow gap semiconductor FeSi and diamagnetic semi-metal CoSi gives rise to interesting metallic alloys with longrange helical magnetic ordering, for a wide range of intermediate concentration. We report various interesting magnetic properties of these alloys, including low temperature re-entrant spin-glass like behaviour and a novel inverted magnetic hysteresis loop. Role of Dzyaloshinski-Moriya interaction in the magnetic response of these non-centrosymmetric alloys is discussed. Typeset using REVTEX

متن کاملStructure and Magnetic Properties of Oxide Nanoparticles of Fe-Co-Ni Synthesized by Co-Precipitation Method
Oxide nanoparticles of Fe-Co-Ni were prepared in six different compositions by co-precipitation method. The as-synthesized nanoparticles were characterized by X-Ray Diffraction (XRD), Field Emission Scanning Electron microscope (FESEM), Fourier Transform Infrared (FT-IR) and Vibrating Sample Magnetometer (VSM). It was found that the nanoparticles had mean crystalline size of 30-55 nm and spher...
متن کاملEffect of Cobalt Concentration on Structural and Magnetic Properties of Co-Fe Thin Films
Co-Fe films were electrodeposited on Cu substrate from electrolytes with different Co concentration levels. X-ray diffraction (XRD) was used to investigate the films crystal structures. The results indicate that if the Co concentration is less that the Fe concentration, the cubic structure appears in the films, while the hexagonal structure dominates when the C...
متن کاملEutectic Solidification Limits and Mechanical Properties of Sm-Co-Fe Alloys
Creating a permanent magnet with a higher energy product than existing materials is attractive in order to optimize magnetic performance. The eutectic microstructure of Sm-Co alloys is attractive for magnets since primary rods of the Co-phase can act as a soft magnetic phase in the matrix of the Sm 2 Co 17 hard magnetic phase, forming two-phase magnets. Fe replacement in Sm-Co alloys provides a...
