Along this proposal we pretend to explore the structural and magnetic phase transitions of the two polymorphs of [NH4][Mn(HCOO)3] using single crystal neutron diffraction. We...

The main objective of this proposal is the magnetic structure determination of Cu3Mn2F12.12D2O compound, an antiperovskite-like with the formulae ABX3 ([MnF6][MnF6][Cu(H2O)4]3)....

Competing and anisotropic interactions can lead to molecular systems self-organising as pressure or concentration is varied. We have recently discovered that Sr3Ru2O7 shows...

A triangular lattice of quantum spins is a candidate for a quantum spin-liquid ground state. In a family of organic charge-transfer salts pairs of BEDT-TTF radicals host an...

CeCuAl3 crystallizes in the tetragonal BaNiSn3-type structure (space group I4mm, 107) and orders antiferromagnetically with Néel temperature 2.6 K. CeCuAl3 shows interesting...

The earth copper systems RCu (R = Dy, Ho, Er, Tm) crystallize in the CsCl structure and exhibit multi-k commensurate antiferromagnetic structures due to competing electronic...

We propose to explore the nature of the ordered phases in La2-xSrxCoO4 for x = 0.67 and 0.75. At lower x values this system condenses into short-range incommensurate magnetic...

NdB4 crystallises into a tetragonal structure, where the Nd ions for layers in the ab-plane that are topologically equivalent to the Shastry-Sutherland lattice. Other members...

Skyrmions are topologically protected field configurations with particle-like properties that play an important role in various fields of science. Recently, skyrmions have been...

We propose to study the magnetic and crystal structures of triangular antiferromagnet anhydrous NiI2 which exhibits two magnetic phase transitions at approx. 60 K and 75 K.

Spin fluctuations can be considered as the most plausible candidate to explain the superconducting pairing in iron-based superconductors. The FeAs parent materials exhibit a...

CaBaCo4O7 belongs to a class of polar compounds named 114 where the transition metal (TM) is located on a frustrated network (Kagome+triangular ). Up to know two magnetic...

This proposal is a partial resubmission of the 5-51-460 one, which is currently being carried out. While part of the proposal is running smoothly, experiments in D10 found...

The perovskite iridates R2Ir2O7 are of fundamental interest because from R=Nd to Ho each member exhibits a metal insulator transition between T(MI)= 117 (Sm) and 141 (Ho)...

The non-centrosymmetric CeCoGe3 compound exhibits interesting physical properties. It orders antiferromagnetically with three ordering temperatures TN1=21K, TN2=12K and TN3=8K....

Nd2RhIn8 belongs to a large family of structurally closely related materials characterized by the general formula RmTnX3m+2n. This broad family of compounds is of particular...

This series of compounds [(CnH2n+1)4N][FeIIICl4]n exhibits several nuclear phase transitions as a consequence of the high mobility of the amine-based countercation. The...

There is a long controversy about the magnetic behavior of Bi2CuO4. Many studies have been devoted to this material using a wide spread of techniques without being able to come...

We propose to perform a single crystal diffraction measurement on MgV2O4. Our single crystal measurements using neutrons and susceptibility indicate the presence of a second...

Mott-type substances with strong electronic correlations and cubic NaCl structure (e.g. MnO, FeO, CoO) undergo a pressure-induced metal-dielectric transition at around 100 GPa,...
