A novel set of superconducting main precession coils has been built and installed in the Jülich-neutron spin-echo (J-NSE) spectrometer at the Heinz Maier-Leibnitz Zentrum (MLZ) in Garching. These unique new coils comprise a field-integral optimizing field shape, fringe field compensation, and high stability [...]

Using complementary polarized and unpolarized single-crystal neutron diffraction, we have investigated the temperature-dependent magnetic structures of Eu0.5Ca0.5Fe2As2. Upon 50% dilution of the Eu sites with isovalent Ca2+, the Eu sublattice is found to be still long-range ordered below TEu=10 K, in the A-type antiferromagnetic (AFM) structure. [...]

We present bulk and neutron scattering measurements performed on the isotopically enriched 154Sm2Ti2O7 and 154Sm2Sn2O7 samples. Both compounds display sharp heat capacity anomalies, at 350 and 440 mK, respectively. [...]

Microbubble-enhanced sonothrombolysis is a promising approach to increasing the tolerability and efficacy of current pharmacological treatments for ischemic stroke. Maintaining therapeutic concentrations of microbubbles and drugs at the clot site, however, poses a challenge. [...]

CeRhSi3 is a superconductor under pressure coexisting with a weakly antiferromagnetic phase characterized by a Bragg peak at →q0=(∼0.2,0,0.5) [N. Aso et al., J. [...]

For the last few decades, researchers have been intrigued by multipolar ordering phenomena and related quantum phasetransitions in heavy-fermion Kondo systems. However, a criticality induced by substitution level (x), temperature (T), or magneticfield (B) is poorly understood even in the prototypical material, Ce1−xLaxB6, despite a large collection of experimental results isavailable.

Microgels are solvent-swollen nano- and microparticles that show prevalent colloidal-like behavior despite their polymeric nature. Here we study ultra-low crosslinked poly(N-isopropylacrylamide) microgels (ULC), which can behave like colloids or flexible polymers depending on dimensionality, compression or other external stimuli. [...]

We present a study on a bicontinuous microemulsion exposed to a planar hydrophilic surface with a flow field along the interface using neutron reflectometry. The microemulsion displays a lamellar interface ordering. [...]

The AMPA receptor GluA2 belongs to the family of ionotropic glutamate receptors, which are responsible for most of the fast excitatory neuronal signalling in the central nervous system. These receptors are important for memory and learning, but have also been associated with brain diseases such as Alzheimer's disease and epilepsy. [...]
