The weakly coupled spin cluster systems provide a fertile ground to study both zero-dimensional quantum and three-dimensional collective magnetism. Such spin cluster systems...

The high ionic conducting delta-phase of Bi2O3 can be stabilized at ambient temperature in a range of compositions, viz., (Bi1-xYx)2O3 (x=0.1 -0.5). We would measure inelastic...

We propose to investigate the spin fluctuations in a candidate S=5/2 Kagome lattice. Previous neutron diffraction has found that RbFe2F6 maybe a good realization of a Kagome...

To understand the thermal conductivity suppression within PGEC titanate oxide thermoelectrics we hope to complement theoretical calculations performed on several perovskites...

Recently, a new family of compounds A2R3Sb3O14 (A = Mn, Mg, Zn, Co; R = rare-earth ions) has been discovered.when the non-magnetic rare-earth ions (R = La3+, Y3+, Lu3+) occupy...

The high ionic conducting delta-phase of Bi2O3 can be stabilized at ambient temperature in a range of compositions, viz., (Bi1-xYx)2O3 (x=0.1 -0.5). We would measure inelastic...

Here we propose to measure the phonon density of states in nanocrystalline samples of YAG:Cr. Our parallel luminscence measurements have revealed dramatic changes in the phonon...

Recently new molecular based magnets Li2AMo3O8 (A = In and Sc), where Mo3O8 clusters form S = 1/2 triangular lattice Heisenberg antiferromagnet, were synthesized....

We propose to measure phonon density of states in LixFePO4 (x = 0.3, 0.6 and 1.0; three sample) from 300 to 1000 K to understand the role of lithium disorder with change in x...

Although stuffing in the quantum spin ice (QSI) Yb2Ti2O7 has been shown to play a vital role inthe selection of a ground state, the only study to address such disorder was...

We propose to map out the spin excitations in La2O2FeOSe2 using the MARI chopper spectrometer on a powder sample. Although the structure of La2O2FeOSe2 has some similarities to...

The 'non-magnetic' ground state of a Kondo ion is generally believed to consist of the localised spin surrounded by a compensating cloud of conduction electrons coupled...

Molecular nanomagnets containing 4f ions are attracting an increasing interest because of their large magnetic anisotropy and slow relaxation of magnetization originating from...

To determine the crystal fields of hexagonal RRh3 (R=Pr, Nd) compounds showing ferromagnetic transitions at TC=3 and 6 K, respectively, we plan to perform inelastic neutron...

The proposal addreses the compounds PrPtAl and YbNiSn. Both systems are canted ferromagnets with both materials undergoing moment reorientation transitions as a function of...

This proposal is a continuation of Rapid Access experiment RB170007 done on MARI in September 2016, as recommended by MARI beam scientists. This experiment was done to establish...

Brownmillerites of the form ABO2.5 constitute an interesting variant of oxygen deficient perovskites, with magnetic ions stabilized in alternate octahedral and tetrahedral...
