Pyrochlore oxides of the type A2B2O7 (where A = trivalent rare earth, B = tetravalent transition metal element) can form geometrically frustrated magnets displaying a range of...

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...

Superconductivity and the charge density wave (CDW) are two very different cooperative electronic phenomena. However, both occur because of Fermi surface instabilities and...

Spin liquids are phases of matter where, in spite of strong near neighbour magnetic interactions, long range magnetic ordering is prevented due to conflicting interactions....

Rcently the NFL behaviour near an antiferromagnetic quantum critical point (AFQCP) has been investigated extensively. Very recently, we have investigated, for the first time,...

We propose muSR experiments to study topological superconductivity in the low-carrier-density superconductor Sn1-xinxTe and Rashba-type non-centrosymmetric superconductor...

Superconductivity and the charge density wave (CDW) are two very different cooperative electronic phenomena. However, both occur because of Fermi surface instabilities and...

CeCu2Si2 was the first heavy fermion superconductor and unlike those previously discovered, which were well explained by BCS theory, CeCu2Si2 is an unconventional...

Very recently Sato et al., JPSJ 2018 have investigated superconductivity in the single crystals of CeIr3 (Tc = 3.4 K, which is highest among Ce compounds), which shows a weak...

: Recently it has been reported from specific heat, resistivity, and susceptibility measurements that CeRh2Ga exhibits very interesting NFL behaviour. The specific heat divided...

The molecular magnetic system Mo3S7(dmit)3 is a semiconductor with a charge gap of around 100 K and no magnetic transition or spin freezing down to 2 K. In the crystal structure...

Two molecular magnetic systems are considered which show low-temperature ordered states. One of them is F4BImNN, a nitronyl nitroxide radical magnet, an excellent realization of...

The field of non-centrosymmetric (NCS) superconductors has gathered much attention in recent years owing to its unconventional behavior. The lack of inversion symmetry in this...

-The quasi-kagome Kondo lattice CeRhSn exhibits quantum criticality induced by geometrical frustration. Divergent Grüneisen ratios provide evidence for a zero-field QCP. The...

It is proposed to use ZF and TF muSR to study the low temperature, low field part of the phase diagram of Ba3CuSb2O9, a system with a uniform triangular lattice of S=1/2 Cu ions...

In 2005 we carried out muon spin relaxation (muSR) experiments in Pr(Os1-xRux)4Sb12 alloys at KEK, Tsukuba, Japan, to investigate the time-reversal symmetry breaking found in...

Gaining control of the building blocks of magnetic materials will enable the design and growth of bespoke magnetic devices. However, the ability to tune the magnetic...

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

Spinels, which have formula AB2X4 and crystallise in the cubic space group, exhibit a rich landscape of structural, magnetic and electronic properties. However, superconducting...

Our recent µSR measurements on a polycrystalline sample of Ru7B3 has shown that this material is an excellent example of broken time reversal symmetry on entering the...
