More than four decades ago A. F. Andreev predicted theoretically the existence of quantum statesof 3He atoms on free surface of liquid 4He . In other words, at low temperatures,...

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...

The room temperature crystal structure of TbInO3 realises a geometrically frustrated two-dimensional triangular lattice of Tb3+ J = 6 cations. We have prepared ~ 6 g of high...

Ce3Co4Sn13 is a cubic heavy Fermion system which resides close to a magnetic instability.Under ambient conditions Ce3Co4Sn13 exhibits an extremely large (4 J/mol Ce K2) peak in...

Recently, we have found a new multiferroics material FeTe2O5Br, with simultaneous ferroelectric and incommensurate magnetic orderings appear at TN = 11 K. Our neutron...

Quantum spin liquid (QSL) is a long-sought goal of condensed matter physics because of its connection to the microscopic mechanism of high-Tc superconductivity and non-trivial...

In recent years, there has been a great interest in quantum spin liquid (QSL). The QSL state is characterized by no conventional order parameter associated with a broken...

Magnetic chains are playgrounds for unconventional physics but emergence of 1D order in cannonical systems is associated with full 3D magnetic order. Uniquely, below 1.6 K,...

Our recent WISH study of the low temperature longe range ordered magnetic structure of the Fe19 single molecule magnetic system with S=35/2 produced an easy spin axis that is at...

Quantum phase transitions have recently received a lot of interest in various different fields of physics and the emergent universal properties have been studied in very...

Among the intense research on quantum spin liquid states, the Kitaev model has attracted great attention. Compounds consist of honeycomb layers with strong spin-orbit coupling,...

We propose to investigate the resonance peak in superconducting CeCoIn5 as a function of applied field. Preliminary low resolution cold triple-axis data has been suggestive that...

One dimensional Heisenberg antiferromagnetic (1DHAF) chain systems continue to attract interest as there are several outstanding questions about the nature of the propagation of...

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...

We propose measurements of the Bose-Einstein Condensate (BEC) fraction n0 of solid helium confined in porous media. A superfluid fraction in solid helium in Vycor, in aerogel...

Recent observation of AFM transition at 1.3 K in Sr2YIrO6 with Ir in 5+ valence state has motivated research interests in the double perovskite Sr2TIrO6. Usually Ir5+ with a...

We propose to measure the neutron diffraction pattern of a single crystal sample of SrEr2O4, using the WISH diffractometer. As the magnetic Er ions in this compound are linked...

In recent work Moessner and colleagues have demonstrated that thermally induced defects in spin ice behave as emergent magnetic monopoles. Within the material there exist...

In a typical magnetic material the interactions between neighbouring magnetic moments will tend to lead to their ordered alignment throughout the entire structure as it is...
