Magnetoelectric Néel anisotropies
نویسنده
چکیده
The applicability of Nkel's pair model to metallic 3d surfaces and interfaces is explained in terms of the tight-binding momentstheorem. The Nee1 model reproduces itinerant magnetism so long as the band structure is approximated by third-moment atomic-pair contributions. This establishes an atomic NCel description of interfaces and impurities. The NCel parameter g depends on the d-band filling and, t o some extent, on the atomic structure.

magnetic dispersion and anisotropy in multiferroic BiFeO3.
We have determined the full magnetic dispersion relations of multiferroic BiFeO3. In particular, two excitation gaps originating from magnetic anisotropies have been clearly observed. The direct observation of the gaps enables us to accurately determine the Dzyaloshinskii-Moriya (DM) interaction and the single ion anisotropy. The DM interaction supports a sizable magnetoelectric coupling in thi...
متن کاملEffect of substitutional doping on the Néel temperature of Cr2O3
First-principles calculations are used to explore the possibility of enhancing the Néel temperature T N of the magnetoelectric antiferromagnet Cr 2 O 3 by substitutional doping. We describe the electronic structure of transition metal (V, Ti, Mn, Fe, Co, and Ni) and anion (N and B) impurities and evaluate their effect on the exchange interaction. We find that, although transition-metal impuriti...
متن کاملTowards a Microscopic Model of Magnetoelectric Interactions in Ni3V2O8
We develop a microscopic magnetoelectric coupling in Ni3V2O8 (NVO) which gives rise to the trilinear phenomenological coupling used previously to explain the phase transition in which magnetic and ferroelectric order parameters appear simultaneously. Using combined neutron scattering measurements and first-principles calculations of the phonons in NVO, we identify eleven phonons which can induc...
متن کاملUnderstanding and designing magnetoelectric heterostructures guided by computation: progresses, remaining questions, and perspectives
Magnetoelectric composites and heterostructures integrate magnetic and dielectric materials to produce new functionalities, e.g., magnetoelectric responses that are absent in each of the constituent materials but emerge through the coupling between magnetic order in the magnetic material and electric order in the dielectric material. The magnetoelectric coupling in these composites and heterost...
متن کاملSelf-Biased 215MHz Magnetoelectric NEMS Resonator for Ultra-Sensitive DC Magnetic Field Detection
High sensitivity magnetoelectric sensors with their electromechanical resonance frequencies < 200 kHz have been recently demonstrated using magnetostrictive/piezoelectric magnetoelectric heterostructures. In this work, we demonstrate a novel magnetoelectric nano-electromechanical systems (NEMS) resonator with an electromechanical resonance frequency of 215 MHz based on an AlN/(FeGaB/Al2O3) × 10...
