We propose to measure spin waves in detwinned SrFe2As2, combined with our data on detwinned BaFe2As2 this allows us to understand if magnetic excitations in the two systems can...

The rare-earth frustrated magnets with dipole-octupole doublet trigger intense research interests due to their exotic quantum phases including spin fragmentation. The newly...

the correlation degree in 122 iron pnictides mainly depends on the electronoccupancy of each orbital and that by doping electrons the correlation decreases monotonically. This...

Since magnetism in Fe-based superconductors (SCs) show many similarities to that in Cr, investigation of the overall spin dynamics of antiferromagnetic (AF) metal will give...

ACo2As2 (A=Ba, Sr, Ca) are end members of Co doped Ba-122 family. Understanding the magnetic behavior of these end members can help us to understand the magnetic properties of...

We have devoted much efforts to investigating the doping evolution of the magnetic excitations in electron doped BaFe2-xNixAs2 (x=0-0.6). Spin excitations for x=0-0.6 have been...

We recently observed a resonant spin excitation in Ba0.6K0.4Fe2As2, one of the newly discovered iron arsenide superconductors with Tc=38K, on MERLIN. This demonstrates that the...

Topological materials get extensive attention in last three decades. HgCr2Se4 is one of those materials being a Weyl semimetal which is induced by time-reversal symmetry...

The Vanadium spinels provide ideal systems to study the interactions between spin, lattice and orbital degrees of freedom. The magnetic V3+ ions are antiferromagnetically...

The relationship between spin fluctuations and superconductivity is an important issue in condensed matter physics. Part of evidence suggesting direct correlation between spin...

At low temperatures FeSi is a non-magnetic insulator, but becomes a metallic paramagnet for T > 300K. It has been proposed to be a Kondo insulator in which local electron...

Magnetism is believed to be linked to superconductivity in cuprates and iron pnictides. However while the parent compounds of cuprates are Mott insulators, the parent compounds...

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,...

We find unusual antiferromagnetic order in Cu heavily overdoped BaFeCuAs2 with the order wave vector at (0.5 0.5 1). This anitiferromagnetic signal cannot come from the parent...

Antimony sulfo-iodide (SbSI) exhibits strongly-coupled photoconductive, semiconducting, and ferroelectric properties. Until the discovery of the lead-oxide ferroelectric relaxor...

The proposal aims to investigate the formation of magnetic stripes in La2-xSrxCoO4. Recent measurements have revealed an hourglass magnetic spectrum at x=1/3. The question we...

We find unusual antiferromagnetic order in Cu heavily overdoped BaFeCuAs2 with the order wave vector at (0.5 0.5 1). This anitiferromagnetic signal cannot come from the parent...

FeSe has a superconducting ordering temperature Tc = 9K. Superconductivity coexists with nematic order which is manifest most clearly by an orthorhombic distortion which sets in...

Very recently, bulk superconductivity has been found at Tc = 43 K in the layered compound FeSe intercalated with Li ions and amide and ammonia molecular groups. We propose to...

Yttrium Iron Garnet (YIG) is a material with extremely wide ranging applications. It is a ferrimagnetic spinel with the narrowest ferromagnetic resonance linewidth of any known...
