چکیده

The Kondo lattice antiferromagnet YbNiSi3 was investigated by neutron scattering. The magnetic structure of YbNiSi3 was determined by neutron diffraction on a single-crystalline sample. Inelastic scattering experiments were also performed on a pulverized sample to study the crystalline electric field (CEF) excitations. Two broad CEF excitations were observed, from which the CEF parameters were determined. The temperature dependence of the magnetic susceptibility χ and the magnetic specific heat Cmag were calculated using the determined CEF model, and compared with previous results.

Polarized neutron scattering studies of the kagomé lattice antiferromagnet KFe3(OH)6(SO4)2

We report polarized neutron scattering studies of spin-wave excitations and spin fluctuations in the S=5/2 kagomé lattice antiferromagnet KFe3(OH)6(SO4)2 (jarosite). Inelastic polarized neutron scattering measurements at 10 K on a single crystal sample reveal two spin gaps, associated with in-plane and out-of-plane excitations. The polarization analysis of quasi-elastic scattering at 67 K shows...

The Ground State of the Spin-12 Kagomé Lattice Antiferromagnet: Neutron Scattering Studies of the Zinc-Paratacamite Mineral Family

The magnetic properties of the geometrically frustrated quantum magnets clinoatacamite, Cu2(OH)3Cl, and herbertsmithite, ZnCu3(OH)6Cl2, are studied by means of neutron scattering measurements as well as specific heat, susceptibility, and magnetization measurements. These materials are studied to investigate the nature of the ground state of the spin2 kagomé lattice antiferromagnet, as such a sy...

Neutron Scattering, Magnetometry, and Quantum Monte Carlo Study of the Randomly-Diluted Spin-1/2 Square-Lattice Heisenberg Antiferromagnet

We have successfully grown sizable single crystals of La2Cu1−z(Zn,Mg)zO4 with up to nearly half of the magnetic Cu sites replaced by non-magnetic Zn and Mg. Neutron scattering, SQUID magnetometry, and complementary quantum Monte Carlo (QMC) simulations demonstrate that this material is an excellent model system for the study of site percolation of the square-lattice Heisenberg antiferromagnet (...

YbNiSi3: An antiferromagnetic Kondo lattice with strong exchange interaction

We report on the structural, thermodynamic, and transport properties of high quality single crystals of YbNiSi3 grown by the flux method. This compound crystallizes in the SmNiGe3 layered structure type of the Cmmm space group. The general physical behavior is that of a Kondo lattice showing an antiferromagnetic ground state below TN=5.1 K. This is among the highest ordering temperatures for a ...

Spin waves in the frustrated kagomé lattice antiferromagnet KFe3(OH)6(SO4)2.

The spin wave excitations of the S=5/2 kagomé lattice antiferromagnet KFe3(OH)6(SO4)2 have been measured using high-resolution inelastic neutron scattering. We directly observe a flat mode which corresponds to a lifted "zero energy mode," verifying a fundamental prediction for the kagomé lattice. A simple Heisenberg spin Hamiltonian provides an excellent fit to our spin wave data. The antisymme...
