Superconducting ammonia-rich metal/ammonia intercalates of FeSe
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... -
Muon spin relaxation study of R2RuO5 (R = Pr, Nd, Sm, Tb)
R2RuO5 (R = Pr, Nd, Sm, Gd, Tb) are known to exhibit interesting physical properties. They all show magnetic ordering between 8 ¿ 24 K. They also show large Sommerfeld... -
Spin dynamics of the Heisenberg triangular antiferromagnet KCrO2
The members of the series ACrO2 (where A=Li, Na, K) comprise well-decoupled, highly ideal triangular planes containing isotropic spins. While the A=Li and Na materials have been... -
Layered lithium iron selenide hydroxide superconductors
FeSe is a superconductor below 8.5 K. Very recently, we have found superconductivity in a wide compositional range in a series of layered lithium iron selenide hydroxides.... -

We aim at performing temperature (2-300K) and magnetic field (0-5T) dependent muon SR on a 1X1 cm2 mosaic, made of 4* 5x5x2 mm3 TbMn0.98Fe0.02O3 single crystals (largest area... -
Disorder-induced suppression of magnetic ordering in frustrated Co(1/3-d)NbS2
Magnetic ordering in frustrated systems with large magnetic interactions remains a key question in condensed matter physics. Despite strong theoretical and experimental quest to... -

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... -
Probing the magnetic ground state in one dimensional magnetic systems Ba3CrS5...
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... -
Fluctuating stripes in an insulating hole-doped antiferromagnet
In a recent letter to Nature, Boothroyd and coworkers have shown that the well known hour-glass spectrum, previously observed in some cuprate materials, occurs in a hole doped... -
Muon spin rotation study on PrTSi3 (T = Ir, Rh and Ru)
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... -
muSR studies of expanded fullerides across the superconductivity dome
FCC Cs3C60 can be driven to a bulk superconducting state without symmetry change by the application of pressure. Its Tc passes through a maximum of 35 K at 6 kbar. We have been... -
Magnetic ordering and correlation phenomena in the rare-earth RT2Al10 compounds
RT2Al10 is a new series of rare-earth-based ternary aluminide compounds that show a variety of magnetic phenomena. This proposal is for a muSR study on three of its members to... -
Studying the metamagnetism of FeCl2 and FeBr2 using HiFi
Work on the iron halides FeX2 has led to the models of A-type antiferromagnetism and the tricritical point in magnetic systems. Here we wish to carry out decoupling experiments... -
A MuSR study of the superconductivity in ACa2Fe4As4F2 (A = K, Rb, Cs)
The iron pnictide (Fe-Pn) superconductors were the second family of high temperature superconductors to be discovered and have a number of different crystal structures. We... -
Soft chemistry tuning between magnetism and superconductivity in K{1-x}Fe{2-y...
Traditional high-temperature synthesis techniques can be used to vary the composition of K{1-x}Fe{2-y}Se2 up to certain limits. We have found a way to extend the limits on the K... -
Probing superconductivity, static magnetism and light ion diffusion in molecu...
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... -

Spin correlations of a triangular-lattice quantum-spin-liquid candidate
A quantum spin liquid (QSL) shows no magnetic order down to zero temperature but the spins are highly entangled. More and more interests are attracted to 2D spin-1/2... -
Direct measurement of magnetoelectric coupling - a new room temperature multi...
We have recently performed muon measurements on a member of a new class of multiferroic materials. We have shown that there is hysteretic behaviour to the internal field... -
