Giant saturation magnetization effect in epitaxial Fe16N2 thin films grown on MgO (001) substrate
Nian Ji, Valeria Lauter, Hailemariam Ambaye +1
Whether αdouble prime-Fe16N2 possesses a giant saturation magnetization (Ms) has been a daunting problem among magnetic researchers for almost 40 years, mainly due to the unshakabl…
Direct Observation of Giant Saturation Magnetization in Fe16N2
Nian Ji, Valeria Lauter, Cheng-Jun Sun +8
Magnetic materials with giant saturation magnetization have been a holy grail for magnetic researchers and condensed matter physicists for decades because of its great scientific a…
Polarized neutron reflectometry study of Fe16N2 with Giant Saturation Magnetization prepared by N Inter-diffusion in Annealed Fe-N Thin Films
Nian Ji, Valeria Lauter, Hailemariam Ambaye +5
We report a synthesis route to grow iron nitride thin films with giant saturation magnetization (Ms) through an N inter-diffusion process. By post annealing Fe/Fe-N structured film…
Heavy Fermion metal Fe16N2 and its giant magnetic moment
Nian Ji, Xiaoqi Liu, Jian-Ping Wang
A new model is proposed for the strong ferromagnetism associated with partially localized orbitals in the Fe16N2 metallic system which draws substantially from models of heavy ferm…
