Materials with large caloric effects offer the opportunity to replace current refrigeration technologies that require the compression of hazardous gases. Whilst magnetocaloric...

The compounds we want to study belong to the well-known tetragonal RM2X2 family (R: rare earth, M: d element, X: Ge, Si). In EuCu2(SixGe1-x)2, the Eu valence changes, as a...

Weyl magnon in the chromium-based breathing pyrochlores is a recently predicted novel magnetic excitation state. Similar to its anolog, Weyl fermion in the electric systems,...

The Dzyaloshinskii-Moriya interaction is thought to be responsible for the stabilization of weak ferromagnetism or magnetic spiral states in a number of diverse systems. An...

The Sr(4-x)Ca(x)Mn2CoO9 compounds are geometrically frustrated transition metal (TM) oxide, which present a variety of interrelated magnetic behavior. The (Mn,Co) TM form a...

Superconductivity in iron-based materials occurs in close proximity to a long-range ordered magnetic phase. In the iron pnictides, uniaxial pressure shifts the magnetic ordering...

Single-molecule magnets (SMM) exhibiting slow magnetic relaxation have attracted increasing interest, both from a fundamental point of view, and for the potential practical...

The A2B2O7 pyrochlore family, where A is a rare earth ion and B=Ti, Sn, is one of the most prolific series of compounds presenting magnetic frustration. The geometric Fd-3m...

We wish to measure the magnetic excitations and subgap states in a doped (x=0.06) spin ladder using MERLIN. The purpose of the measurements is to ascertain the relationship...

The relationship between spin fluctuations and superconductivity is of paramount importance in understanding the iron-based superconductors. We have recently investigated the...

The spin-1 antiferromagnetic chain (or Haldane chain) is a model system which was predicted by Duncan Haldane to have gapped magnon excitations due to an underlying topological...

Nd2Zr2O7 (NZO), synthesized and supplied to us by Tokura and Onose, is a new candidate spin ice while Pr2Zr2O7 (PZO) if anything even more promising is supplied to us by...

We recently observed a resonant spin excitation in Ba1-xKxFe2As2 (x=0.4), one of the newly discovered iron arsenide superconductors with Tc=38K, on MERLIN. This demonstrates...

We have investigated the magnetic structure and crystal field excitations (CEF) of CeT2Al10 (T=Os and Ru). The observed magnetic moment along the c-axis does not agree with that...

The spin excitations in superconducting LiFeAs have been found evolved from incommensurate peaks to commensurate peak at low energy. But the spin resonance is still not clear in...

With the degenerate ground states by the competition between the interacting energies and geometrical properties of the crystal lattice at a specific given site, the...

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

Recently it has been reported that YbAl3C3 undergoes an antiferromagnetic quadrupolar ordering transition at 80 K, Further study by Ochiai et al. revealed that the transition at...

Cobalt Oxide has the face centered cubic structure above the antiferromagnetic transition of 300 K. The magnetic moments are composed of both spin and orbital contributions....

CeRu2Al10 belongs to the CeT2Al10 family (T: Ru, Os, Fe), which exhibits Kondo-insulator behavior and high magnetic ordering temperature (TN=27K), with an unusual competition of...
