Autor: Vladimir Hutanu, Yasujiro Taguchi, Vilmos Kocsis, Astrid Schneidewind, Rajesh Dutta, Henrik Thoma, Igor Radelytskyi, Yoshinori Tokura, Yusuke Tokunaga

Publikováno v: Physical Review B. 104

We report a spin-wave study on multiferroic ${\mathrm{Ba}}_{2}{\mathrm{CoGe}}_{2}{\mathrm{O}}_{7}$ under magnetic fields up to 12 T using low-energy inelastic neutron scattering. In-plane transverse $({T}_{1})$ spin-wave modes are highly dispersive a

Phys Rev B

We use inelastic neutron scattering to study the effect of a magnetic field on the neutron spin resonance (Er = 3.6 meV) of superconducting FeSe (Tc = 9 K). While a field aligned along the in-plane direction broadens and suppresses the resonance, a c

We use neutron scattering to show that ferromagnetic (FM) phase transition in the two-dimensional (2D) honeycomb lattice ${\mathrm{CrI}}_{3}$ is a weakly first order transition and controlled by spin-orbit coupling (SOC) induced magnetic anisotropy,

Rearrangement of uncorrelated valence bonds evidenced by low-energy spin excitations in YbMgGaO4

Autor: Sebastian Bachus, Alexandre Bertin, Yoshifumi Tokiwa, Philipp Gegenwart, Astrid Schneidewind, Yuesheng Li, Benqiong Liu, Igor Radelytskyi, Alexander A. Tsirlin

Publikováno v: Physical review letters 122(13), 137201 (2019). doi:10.1103/PhysRevLett.122.137201

DC-magnetization data measured down to 40 mK speak against conventional freezing and reinstate YbMgGaO$_4$ as a triangular spin-liquid candidate. Magnetic susceptibility measured parallel and perpendicular to the $c$-axis reaches constant values belo

EMR studies of the internal motion of Mn4+ ions in the Sr overdoped (La1−xSrx)(Ga1−yMny)O3 (x/y up to 8) supplemented by magnetic and optical spectroscopy measurements

Publikováno v: Journal of Magnetic Resonance. 255:77-87

The effect of the Sr doping on electronic structure in single crystals of (La(1-x)Sr(x))(Ga(1-y)Mn(y))O3 solid solutions (LSGM) is investigated by means of electron magnetic resonance (EMR). The EMR results are supplemented by magnetic susceptibility
