Abstract α -RuCl 3 is a major candidate for the realization of Kitaev quantum spin liquid, but its zigzag antiferromagnetic order at low temperatures indicates deviations from model. We have quantified Hamiltonian by resonant inelastic x-ray scattering study Ru L absorption edge. In paramagnetic state, quasi-elastic intensity magnetic excitations has broad maximum around zone center without any...
A microstrip line fabricated on a single crystal hexagonal -type ferrite substrate was utilized to achieve phase shifts of 65 /cm at -band with an external bias field of only 100 Oe. This approach utilizes the rapid variation of the -type ferrite tensor permeability near the ferromagnetic antiresonance frequency. The magnetic and microwave properties of the substrate material were characterized...
The strong coupling between antiferromagnetism and ferroelectricity at room temperature found in BiFeO3 generates high expectations for the design and development of technological devices with novel functionalities. However, the multi-domain nature of the material tends to nullify the properties of interest and complicates the thorough understanding of the mechanisms that are responsible for th...
The emerging material class of complex-oxides, where manipulation of physical properties lead to new functionalities at their heterointerfaces, is expected to open new frontiers in Spintronics. For example, SrRuO3 is a promising material where external stimuli like strain, temperature and structural distortions control the stability of electronic and magnetic states, across its magnetic phase t...
We reconsider the problem of the anomalous Hall effect in ferromagnetic SrRuO3, incorporating insights from the recently developed theory of Weyl semimetals. We demonstrate that SrRuO3 possesses a large number of Weyl nodes, separated in momentum space, in its bandstructure. While the nodes normally do not coincide with the Fermi energy, unless the material is doped, we show that even the nodes...
Magnetic noise in electrical machines and transformers are a large portion of the total noise of the device. Part of this magnetic noise is caused by the deformation of the ferromagnetic laminations due to the magnetic field. This effect is called magnetostriction, and it strongly depends on the applied magnetic field, the material properties and external pressure to the material. A strain gaug...
