By polarized neutron reflectometry we want to investigate the magnetic field profile in Y(1-x)PrxBa2Cu3O7/La(2/3)Ca(1/3)MnO3 high-Tc superconductor/ferromagnet superlattices. In...

A recent experiment (RB820171) unexpectedly revealed that a sample of beta-Mo2N exhibited a number of extra reflections at 4 K; a temperature below the superconducting critical...

We would like to complete the phase diagram by measuring one more sample of Fe1+xTe for x = 14 %, which represents a point at one extreme of the phase diagram. The simple binary...

We will use POLARIS to determine the structures of the high temperature superconducting intercalates obtained by the reactions between FeSe and deuterated ammonia solutions...

The intermetallic Mo3Sb7 compound exhibits superconductivity at Tc=2 K and exhibits interesting physical properties in the magnetic susceptibility, electrical resistivity and...

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

The iron-based superconductor LiFeAs exhibits a number of unique features distinguishing it from other materials in its class. As yet, these differences are unexplained. This...

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...

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...

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...

Superconductivity (SC) in unconventional superconductors is believed to be related to magnetism. However, in AyFe1.6+xSe2 (A = K, Rb, Cs) system discovered in late 2010, the SC...

We propose to use MERLIN to examine the full magnetic excitation spectrum Chi¿(q,w) of optimally doped Fe based superconductor BaFe1.84Co0.16As2. The primary goal of this...
