Investigation of a frustrated quantum magnet with novel interaction scheme
SrCuTe2O6 consists of a 3-dimensional arrangement of spin-1/2 Cu ions that are coupled into network of isolated triangles,a highly frustrated hyperkagome lattice consisting of... -
What is the cause for the gapped mode in the `BEC' phase of DTN?
Arguably the most-famous quantum phase transition is the Bose-Einstein condensation (BEC) of magnons. It can be studied experimentally in gapped quantum paramagnets when an... -
Non-magnetic impurities in a strong-leg spin ladder
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... -

Quantum-Critical Dynamics of a 3-dimensional Antiferromagnet
We have recently discovered a pressure-induced quantum phase transition (QPT) at 4.3 kbar in the gapped quantum magnet piperazinium hexachlorodicuprate (PHCC) by means of... -
E/T scaling and quantum critical fluctuations in Sr3Ru2O7
Many novel electronic ground states form in close proximity to quantum critical points (QCPs), that is, the point where a continuous phase transition occurs at zero temperature.... -
Transverse field evolution of magnetic excitation spectrum in Nb1-yFe2+y
Our previous neutron scattering on C14 Laves phase compounds Nb1-yFe2+y revealed that a spin-density-wave (SDW) is masking an underlying ferromagnetic (FM) quantum critical... -
Fractionalized spin excitation and crystal electric field study in the rare-e...
A new rare-earth triangular quantum spin liquid (QSL) candidate, YbMgGaO4, has an odd number of electrons per unit cell and spin-orbit entangled effective spin-1/2 (Yb3+).... -
INS study of the exchange couplings and magnetic anisotropies in Ni(II), Mn(I...
SQUID magnetometry is the first and most trivial step when studying magnetic systems. However reliable conclusions can only be made in cases of very simple systems. When the...
