Exploiting spin coherence phenomena in quantum materials is both technologically and fundamentally relevant, particularly in view of recent developments in quantum computing....

We propose zero-field depolarization measurements to investigate the motional dynamics of diamagnetic muonium centers in hafnium oxide (HfO2), tungsten oxide (WO3) and zirconium...

While investigating the ordering and magnetic dynamics in La2-xSrxCoO4 we found some intriguing behaviour for samples with small x, which would imply that the phase diagram is...

A continued study of muonium diffusion in transparent conducting oxides (TCO) are proposed. We have ZF depolarization measurements conducted up to room temperatures for SnO2 and...

At the heart of understanding collective phenomena in condensed matter physics is the search for emergent phases of matter formed by strong frustrations in geometrically...

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...

Properties of graphene that make it an important material are its exceptionally high conductivity, massless fermions and a high velocity of electrons near the Dirac points....

We have performed further measurements on Dy2Ti2O7 and confirmed the observation of magnetic charge transport. Given the time constraints of our previous experiment not all...

Lead Halide perovskite solar cells is one of the most rapidly growing research areas. Since their discovery in 2009, the devices have shown great promise, with efficiencies over...
