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

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...

This proposal is part of our research programme on spin and orbital order in frustrated systems. The spinel FeSc2S4 realises an exotic ¿spin-orbital liquid¿ with no magnetic or...

Mononuclear Ni(II) complexes can be designed to behave as two-level systems and thus play the role of qbits with eventually large coherence time. The objective of this proposal...

Charge density wave (CDW) order has recently been established as a generic feature of high-temperature cuprate superconductors. It occurs near 1/8 doping and has been observed...

Recently, it has been suggested that the First Sharp Diffraction Peak (FSDP) in glasses arises from a quasi-periodicity of void spaces in the structure, that plays the role of...

The ferromagnetic transition Tc=41 K of CeIr3B2 is the second highest Tc recorded after CeRh3B2 in among Ce-based compounds makes it an interesting candidate to investigate...

Praseodymium-based cubic compounds with a 4f2 configuration have attracted much attention. In case the crystalline electric field ground state is a nonmagnetic doublet, the...

One of the major issues in high temperature superconductivity is the nature of the so called pseudogap phase. A related question is whether the pseudogap controls the evolution...

This proposal was submitted on MERLIN (RB1010206) and beam time was allocated on MARI. We have carried out low energy measurements on MARI and found a clear evidence of the spin...

The strontium iridate Sr2IrO4 has recently received a special attention because of its closeresemblance to undoped high-Tc cuprate in terms of structural, electronic, and...

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...

Monometallic complexes of paramagnetic transition metal or lanthanide metal ions have found to exhibit single-molecule magnet (SMM) behaviour with an appreciably enhanced...

Magnetic frustration is the phenomenon of being unable to satisfy all magnetic interactions present in a system. It draws a lot of attention as it is the source of exotic...

The translational and orientational disorder of some liquids can be frozen if they are cooled down quick enough, giving rise to a Structural Glass (SG). But for some molecular...

Very recently, EuCuAs was proposed as an example of a topological semimetal. Our measurements on Wish show that the Eu magnetic structure is incommensurate with a propagation...

Exchange interactions in insulators can be understood in terms of the Andersen exchange picture in which the Hamiltonian has two contributions: (i) a kinetic term characterized...

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...
