We propose to perform neutron powder diffraction experiments on the frustrated triangular lattice anitferromagnet AgFe1-xAlxO2 on WISH. Recently, we have studied magnetic... -
Magnetoelastic coupling effect on multiferroic behaviors in different types o...
We propose to perform high resolution neutron diffraction on powder samples of the frustrated antiferromagnets Ag1-xCuxFe1-yGayO2 using HRPD. CuFe1-yGayO2 and AgFeO2 have... -
The magnetic structures of RMn7O12 (R = Nd, Sm, Dy, Y)
Materials with the perovskite crystal structure are ubiquitous in condensed matter physics. Despite being known for several years, the quadruple perovskites, which afford... -
Structural investigation of a possible magnetically-induced Weyl semi-metal
One of the major themes in solid-state physics is the realisation of exotic types of relativistic electrons which travel at speeds much slower than the speed of light. These... -
Structure and magnetic order of the diamond-kagome planar compound Cu2OSO4
Materials with antiferromagnetic interactions between spins on a triangle lattice inherently exhibit large frustration between similar energy ground states giving rise to novel... -

We propose to perform neutron diffraction experiments on single crystals, 3R-AgFeO2 and 2H-AgFeO2 on WISH. Recently, we have studied magnetic orderings and ferroelectricity of... -
Multiferroic (Ferroelastic/Magnetic) Phase Transitions in KMnF3
KMnF3 perovskite undergoes 3 structural, and two magnetic phase transitions on cooling from 300 K to 2 K. Above 185 K the compound is in the aristotype structure, on cooling... -
Investigation of Crystal and Magnetic Structures in high pressure synthesized...
Three new doubly ordered perovskites NaYMWO6 (M=Mn, Co & Ni) have been synthesized by high pressure and high temperature. Analysis of room temperature laboratory X-ray... -
Unraveling the short-range magnetism in intermetallic core-shell nanoparticle...
Magnetic nanoparticles are currently being investigated comprehensively. Our ball-milled TbCu2 nanoparticles show a core-shell structure in which the core orders... -

We have synthesized the polycrystalline R2BaCuO5 (R = Dy & Ho) and studied its physical properties. Indeed, both the studied compounds exhibit the polarization below rare... -
Electric field effects on the spin correlation length in multiferroic delafos...
In a previous WISH experiment, we have succeeded in determining the incommensurate cycloidal magnetic structure of AgFeO2, which induces a ferroelectric polarization[1].... -
Magnetic structure of the new chiral magnetoelectric Sb2MnO6
Magnetoelectric multiferroics have been recently the focus of a significant research effort. The experiment that we propose explores a new class of "magnetochiral" systems,...
