We propose RF-MuSR experiments focused on confirming the two shallow Mu donor states tentatively observed in single crystalline beta-Ga2O3 samples. This material is a candidate...

The properties of pnictide superconductors can be controlled exquisitely by chemical doping. We have identified some key systems in which to explore this effect which should...

CaAFe4As4 (A = K, Rb, Cs) and SrAFe4As4 (A = Rb, Cs) are the brand new Fe-based superconductors, only reported in 2016 and is abbreviated as “1144” compounds. Tc values of these...

In centrosymmetric heavy-fermion (HF) superconductors Cooper pairs have either singlet or triplet symmetry. Recently a handful of non-centrosymmetric Ce-based HF compounds have...

We propose to study two phases of Na-NH3 intercalated FeSe which have distinct values of Tc, both close to 40 K, but different concentrations of NH3 and quite distinct crystal...

Recently, there has been a significant amount of interest in quantum phase transitions and non-Fermi liquid (NFL) behavior exhibited by heavy-fermion compounds. Interestingly...

We propose to perform zero-field muon spin rotation studies of S=1 honeycomb antiferromagnet BaNi2V2O8 which is an ideal physical realization of the quasi-2D magnetic system....

In 2012 we demonstrated that molecular spacer layers could be intercalated in between FeSe layers resulting in a dramatic enhancement of the critical temperature: FeSe is itself...

Recently we have investigated three new ternary intermetallic compounds PrTSi3 (T = Ir, Rh and Ru) which form in BaNiSn3-type tetragonal structure. The susceptibility exhibits...

Most of the one dimensional spin chain compounds are antiferromagnetic with a rich magnetic phase diagram due to the magnetic frustration. We have synthesized Ba3CrS5 and...

TbMn0.98Fe0.02O3 is an interesting multiferroic material, as the partial substitution of the Jahn-Teller active Mn3+ cation by the non-Jahn-Teller active Fe3+ has remarkable...

Quantum spin liquid (QSL) state is a state that spins are highly entangled and frustrated even at absolute zero temperature, which has attracted lots of attentions due to its...

All known iron-based superconductors comprise layers of FeAs or FeSe with some combination of group I, group II or lanthanide oxide layers, and usually some doping. To make...

The discovery of superconductivity at up to 55 K in a series of iron arsenide and selenide materials has ignited huge interest. These compounds show unique features that are...
