Magnetization Of Sm-Fe-N Thin Films With In-Plane Anisotropy
Am-Fe-N films have been made by dc magnetron sputtering and heating in-situ in nitrogen atmosphere. It is observed that the anisotropy changes from perpendicular to in-plane by nitrogenation. The Curie temperature is about 380 K. Aspects of structure, hysterisis loops, initial magnetization curves and temperature dependence of coercivity are discussed. SQUID magnetometer was used to measure the...
متن کاملAutonomous Repair Mechanism of Creep Damage in Fe-Au and Fe-Au-B-N Alloys
The autonomous repair mechanism of creep cavitation during high-temperature deformation has been investigated in Fe-Au and Fe-Au-B-N alloys. Combined electron-microscopy techniques and atom probe tomography reveal how the improved creep properties result from Au precipitation within the creep cavities, preferentially formed on grain boundaries oriented perpendicular to the applied stress. The s...

متن کاملSuperconductivity in Sm-doped [n]phenacenes (n = 3, 4, 5).
We report here the discovery of a new aromatic hydrocarbon superconductor, Sm-doped chrysene, with Tc ∼ 5 K, and compare its behavior with those measured in the full series of Sm-doped [n]phenacene superconductors, with n = 3, 4, 5, thus determining the trend of Tc as a function of the number of fused benzene rings and for an odd or even number of units.
