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...

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...

There has been a great deal of interest in non-centrosymmetric superconductivity, mainly induced by the discovery of CePt3Si. The presence or lack of inversion has important...

Superconductivity with Tc=33 K has been reported in alkali-doped polyaromatic hydrocarbons (PAHs). The compositions and structures are unknown owing to the multiphase nature and...

Systems that exhibit a high degree of anisotropy have been attracting considerable attention due to unique physical properties. Recently three superconductors (SC), BaIr2Ge7,...

The binary ruthenium pnictides RuAs and RuP exhibit metal-insulator (MI) transition below 200 K and 270 K, respectively, and show an evidence of pseudogap formation in their...

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...

PdxTaSe2 series is an excellent system for the investigation of the interplay between CDW and superconductivity which shows quantum critical point for x = 0.1. Very recently, we...

NbxBi2Se3 is a potential topological superconductor candidate as it preserve Dirac surface dispersion and also superconducting at the same time. It belongs to the Eu...

A unique characteristic of the specific complex order parameters in noncentrosymmetric (NCS) superconductors (SCs) is time-reversal symmetry breaking (TRSB). The intermetallic...

In order to explore quantum spin ice physics, we wish to focus on the non-Kramers Pr-based pyrochlores with general formula Pr2M2O7 (M =Sn, Zr, Hf). There is a recent...

In a recent letter to Nature, Boothroyd and coworkers have shown that the well known hour-glass spectrum, previously observed in some cuprate materials, occurs in a hole doped...

This proposal plans to investigate the superconducting ground state of the Heusler superconductors with a superconducting transition of ~2K. Heusler compounds have attracted a...

Spin–orbit coupling (SOC) is a fundamental interaction in solids that can induce unusual physical properties, from topologically non-trivial insulating states to unconventional...

Quantum spin liquid (QSL) state is a state that spins are highly entangled and frustrated even at absolute zero temperature, which has attracted lots of attentions due to its...

Strong spin-orbit coupling (SOC) has often lead to exotic properties in otherwise banal pool of 'paramagnetic' heavy ion oxides. In this context d4 Ir systems are exciting...

This proposal plans to investigate the destruction of superconductivity by inter-band scattering in Lu_2Fe_3Si_5 doped by Y and Dy. Recent muon spin rotation studies have shown...
