Recently we have investigated Pr2Pd3Ge5 and Pr2Rh3Ge5 compounds which form in the orthorhombic structure. Pr2Pd3Ge5 exhibits two magnetic transitions at TN1 = 7.5 K and TN2 =...

Common d5 pyrochlore iridates, A2Ir2O7 or A2Ir2O6O’, are reported to have long range magnetic order based on muSR experiment. Only Pr2Ir2O7 has been identified as a metallic...

The frustrated pyrochlore Er2Ti2O7 is a rare example of a magnetic system in which quantum fluctuations are capable of selecting a unique ground state out of the macroscopically...

Rare-earth delafossites were recently proposed as promising candidates for the realization of an effective S = 1/2 quantum spin liquid on the triangular lattice [1, 2]. In...

The magnetic properties of a Holmium single ion magnetic system will be studied using implanted muons. The system is based on a polyoxometallate cluster ion that provides good...

Geometrically frustrated magnetic systems have been widely studied in the search for novel quantum states of matter. The fcc lattice Ba2YMoO6 has been shown to be a valence bond...

Quantum spin liquid (QSL) is an ordered spin state which has been destroyed by quantum fluctuations at low temperatures. Low energy excitations of spin liquids are charge...

In superconductors, the inversion symmetry of the crystallographic structure plays a central role in the formation of the Cooper pairs. When inversion symmetry is broken, there...

Among the rare earth titanates and stannates cristallising in the pyrochlore crystal structure, Tb2Ti2O7 is a singular system since its ground state is believed to be a spin...

Using nitronyl nitroxide radicals it is possible to prepare purely organic ferromagnets without inclusion of any transition metal or lanthanide ions. Muons are uniquely...

The investigation of electron correlations in intermetallic alloys is fascinating. At times, depending on the nature and strength of correlations, the compounds exhibit...

Cu-BHT exhibits perfect kagome lattice of Cu2+ and previous combined magnetization and specific heat results suggested the presence of strong spin fluctuations. If there are...

The Shastry-Sutherland lattice (SSL) can be described as a 2D square lattice built up from a network of dimers disposed orthogonally and has been observed in SrCu2(BO2)3....

In recent time a significant effort has been devoted to Bi-based compounds for being potential candidates of topological insulators. Similarly, a number of investigations also...

CeRhIn5 is an antiferromagnetic itinerant magnet which illustrates a temperature and pressure interplay between antiferromagnetism and superconductivity. Recently, it has been...

Ho2-xYxSn2O7 is characterized by degenerate magnetic ground-states, which involve the magnetic structure for x->0 (Spin-Ice phase) and the two-fold degeneracy of the...

Muon spin relaxation will be used to study the low temperature magnetic properties of a new metal-oxalato-framework compound [(C2H5)3NH]2Cu2(C2O4)3. This has a three-dimensional...

PbCuTe2O6 offers the first opportunity to study a 3D quantum spin liquid well modeled by the simple Heisenberg Hamiltonian on a highly frustrated lattice coined...

Strong spin-orbit coupling often leads to exotic properties in otherwise a well understood pool of 'paramagnetic' heavy ion oxides. For a 5d4 system a J=0 total angular momentum...

LiOsO3 is a very unusual metallic ferroelectric. This experiment aims to distinguish between two contrasting possibilities for the ground state of this material which can be...
