We have recently used a combination of PNR and low energy muon spin rotation (LEM) to detect the coexistence of an induced SDW and superconductivity in the superconducting layer...

This experiment proposes to measure the MuSR signal in undoped phthalocyanine (Pc) samples of NiPc, PbPc, FePc and TiOPc, in order to clarify the existence of the paramagnetic...

The new molecular magnet bis(2,3-dimethylpyridinium) tetrabromocuprate (DIMPY) is a strong-leg spin ladder with a quantum critical point at 3 T separating a low-field...

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...

We wish to measure the magnetic excitations and subgap states in a doped (x=0.06) spin ladder using MERLIN. The purpose of the measurements is to ascertain the relationship...

We propose to characterize the two magnetic transitions in Nd0.75Gd0.25Rh3B2 and study the spin dynamics and field induced domain rotation via zero field (ZF) and longitudinal...

Today, about seventy years after Laves, there exists a fairly good knowledge about the basic structural principles of Laves phases but many questions still remain. AMn-type...

Spins on the kagome lattice are one of the most widely investigated topics in frustrated magnetism. This two-dimensional corner sharing triangular lattice offers a...

We aim to continue our investigation of the high temperature magnetic interactions in LaCoO3. Our previous experiment has confirmed magnetic susceptibility data, with a change...

Spin excitations is correlated with superconductivity in high Tc superconductors. The spin excitations in La2-xSrxCuO4 superconductors become weaker in overdoped region and...

This proposal is part of our research programme to explore the interplay of thermal and quantum fluctuations near zero-temperature quantum phase transitions. Here we plan to use...

Iron is a canonical instance of an itinerant electron ferromagnet, and a classic correlated electron system. Our recent data from MAPS contradicts earlier triple-axis data that...

We have discovered an unusual magnetovolume effect in the 6H-perovskite oxides Ba3BiIr2O9 and Ba3BiRu2O9. These compounds contain isolated face-sharing bi-octahedral dimers...

Spin ladders present a class of low dimensional quantum magnets that occupy a regime of subtle behaviour which lies between the stark extremes of a one-dimensional chain or...

The spin excitations in superconducting LiFeAs have been found evolved from incommensurate peaks to commensurate peak at low energy. But the spin resonance is still not clear in...

Ru4+ ions in Li2RuO3 are on a bipartite lattice and have an orbital degeneracy. The four electrons of the magnetic Ru4+ ions in the threefold-orbitally degenerate t2g manifold...

We propose to study cobalt nitride films using PNR with a view to their use in spin injection & spin engineering applications. Such systems have had little attention in the...

We request four days of beam time to conduct zero and longitudinal field measurements on iridate pyrochlores A2Ir2O7 (A = Y, Lu, Nd) in the temperature range 200 K to 2 K and in...

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...

This proposal looks to study the electron spin relaxation using high field ALC measurements in two polymers, which differ only by the non-metal (i.e S or Se) in the polymer...
