Skyrmions, topologically protected nanometric spin vortices, are being investigated extensively in various magnets(1-11). Among them, many structurally chiral cubic magnets host the triangular-lattice skyrmion crystal (SkX) as the thermodynamic equilibrium ...
In this work, we present a neutron Larmor diffraction study of the rare-earth pyrochlores R2Ti2O7 with R = Tb, Dy, Ho. We measured the temperature dependence of the lattice parameter with precision 10(-5), between 0.5 and 300 K in each of the three compoun ...
We report on the spin dynamics and discovery of magnetoelectricity in the coupled-spin tetrahedral compound Cu2Te2O5Cl2. Te-125 NMR measurements show an anomalous resonance frequency shift and a signal wipe-out phenomenon around the Neel temperature T-N = ...
Many exotic metallic systems have a resistivity that varies linearly with temperature, and the physics behind this is thought to be connected to high-temperature superconductivity in the cuprates and iron pnictides1,2,3,4,5,6,7,8,9. Although this phenomeno ...
We report measurements of Shubnikov-de Haas oscillations in single crystals of BiTeCl at magnetic fields up to 31 T and at temperatures as low as 0.4 K. Two oscillation frequencies were resolved at the lowest temperatures, F-1 = 65 +/- 4 T and F-2 = 156 +/ ...
We present high-resolution triple-axis neutron scattering studies of the high-temperature superconductor La1.88Sr0.12CuO4 (Tc=27 K). The temperature dependence of the low-energy incommensurate magnetic fluctuations reveals distinctly glassy features. The g ...
We present high-resolution triple-axis neutron scattering studies of the high-temperature superconductor La1.88Sr0.12CuO4 (T-c = 27 K). The temperature dependence of the low-energy incommensurate magnetic fluctuations reveals distinctly glassy features. Th ...
Novel magnetic materials are constantly emerging. This thesis reports an Electron Spin Resonance (ESR) study on three novel materials of great scientific interest: monoclinic SeCuO3 compound representing a network of tetramers, large assembly of ultrathin ...
The spin-1/2 Heisenberg antiferromagnets in one and two dimensions are important models in quantum magnetism in which many-body effects play a crucial role. Their collective excitations are associated with quasiparticles the interaction of which are diffic ...
The temperature and magnetic field dependent magnetization of the two-dimensional quantum spin system Ni-5(TeO3)(4)Cl-2 has been investigated using single crystals in temperature range 1.8-100 K and in magnetic fields up to 14 T. The magnetization below th ...
