Previous neutron studies of powdered Gd2Ti2O7 (GTO) have shown that despite it relative simplicity as an s-state Heisenberg antiferromagnet, the magnetic structure is a fairly...

Th S = ½ AF spin ladder is one of the most important models in quantum magnetism. While its properties throughout the (H,T)-phase diagram may be considered to be well understood...

The recently discovered new triangular lattice QSL candidate YbMgGaO4 has attracted great interest on rare earth frustrated magnets. Another triangular lattice rare earth...

The rare-earth compound KYbSe2 provides a new chance for the study of frustrated magnets with strong SOC. It resembles YbMgGaO4 in many ways. Our susceptibility and specific...

Recently we have succeeded in synthesizing a new kagome material, CaCu3(OH)6Cl2 0.6H2O. Single crystal X-ray measurements revealed that no site disorder between Ca and Cu sites...

We propose measurements of the elementary phonon-roton (p-r) excitations of liquid 4He confined in porous MCM-41 (45 Å pore diameter) at wave vectors Q ¿ beyond the roton¿, 2.4...

We propose to investigate the magnetic excitation spectra in the three accessible magnetic ordered phases of the quasi-1D S-1/2 Ising-like antiferromagnet SrCo2V2O8 by single...

One-dimensional (1D) S = 1/2 spin chains are a subject of long-standing interest, because conventional long-range ordering can be prevented and novel Luttinger-liquid phase may...

Spin ice (SI) is a state of matter characterized by a residual (Pauling) entropy and unusual correlations. The huge interest in SI materials from the magnetism community stems...

Few studies of Sm pyrochlores are reported in literature. It is believed that these coumpounds remain in a disordered state down to the lowest temperatures, mainly due to the...

Discovery of time-reversal symmetry (TRS) breaking in Re-based noncentrosymmetric (NCS) α-Mn structure compounds has garnered much attention, due to the repeated occurrence...

Th S = ½ AF spin ladder is one of the most important models in quantum magnetism. While its properties throughout the (H,T)-phase diagram may be considered to be well understood...

Ever since the first published consideration of the ground state of a triangular lattice of Ising spins by PW Andersen in the 50's, the pursuit of materials with geometrically...

Recent theoretical analyses of quantum spin ice has revealed the present of a novel magnetic excitation whose quantum properties are analogous to photons. This mode is a...

Usually, magnetic materials can be understood by imagining them as orderly rows of communicating, atomic-sized bar magnets (or "spins") which organize themselves into a...

Geometrically frustrated lanthanide gallium garnets find practical applications as low temperature magnetocalorics, but the competing interactions in these materials may give...

In this continuation proposal, we propose to study the spin excitations of the spin 1/2 square lattice Heisenberg antiferromagnet CAPCC in fields just below its saturation...

Pyrochlore oxides of the type A2B2O7 (where A = trivalent rare earth, B = tetravalent transition metal element) can form geometrically frustrated magnets displaying a range of...

The recently synthesised triangular-lattice rare-earth magnet KErSe2 crystallizes in the similar strucutre as the new quantum spin liquid candidate YbMgGaO4 but with less stie...

Quantum spin liquid (QSL) is a novel state of matter where the spins are highly entangled with one another but fluctuate strongly down to zero temperature. It may be associated...
