In the layered iron-based superconductor YFe2Ge2, a high Sommerfeld ratio of order 100 mJ/mol K^2 and a T^3/2 temperature dependence of the electrical resistivity at low...

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...

Phonon lifetimes in BCS superconductors provide information on the details of the electron-phonon coupling mechanism. In 2008 high-resolution neutron inelastic scattering...

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...

Given the controversy about the magnetic ground state of the recently well studied triangular-lattice antiferromagnet (TLA) YbMgGaO4 due to Mg2+/Ga3+ disorder, we have...

Spin fluctuations of materials close to a quantum critical point (QCP) exhibit anomalous behaviors. Sr3Ru2O7 has been shown to exhibit field-induced spin density wave (SDW)...

This proposal is part of our research programme to explore the experimental manifestation of topological properties of magnetic excitations. The honeycomb ferromagnet is...

Rare-earth Iron garnets (RE3Fe5O12) have been in the focus of active research for the last five decades due to their fascinating properties, such as large magnetostriction,...

In our first measurement of the high energy spectrum of LaCoO3 we observed a signal which is a promising candidate for an electronic transition from the low spin ground state of...

The mineral Libethenite, Cu2PO4OH, is an ideal system in which to study low dimensional quantum magnetism. Its magnetic behaviour is complex but is related to systems with...
