Many illnesses are associated with an alteration of the immune system homeostasis due to a combination of factors, including exogenous bacterial insult, endogenous breakdown (e.g. development of a disease that results in immuno suppression), or an ex

Unpolarized and polarized neutron diffraction by a single crystal have been used to study the magnetization distribution in the paramagnetic phase of cobalt oxide CoO. Highly accurate magnetic structure factors have been measured using the classical

The magnetic susceptibility and the electron spin resonance in the X-band of the transition metal oxide compound MgVO 3 are reported. We show that this compound, made of weakly coupled infinite chains of VO 5 pyramids, behaves as a S = 1/2 one-dimens

Magnetic resonant x-ray scattering experiments at the $\mathrm{Mn}K$ edge have revealed the occurrence of two different resonances in antiferromagnetic ${\mathrm{RbMnF}}_{3}.$ Below the K edge, at the $3d$ threshold, the resonance profile is consiste

The vanadium oxide bronze η-Na x V 2 O 5 (x = 1.286) crystallizes in the monoclinic system with an original structure built up of layers formed by VO 5 square pyramids and VO 4 tetrahedra parallel to the (010) plane, with the Na atoms lying between

We present an inelastic neutron scattering study performed throughout the field-induced magnetic phase occurring between H c 1 ≃ 3.5 T and H c 2 ≃ 4.5 T in the spin 1/2 alternating antiferromagnetic chain compound Cu ( NO 3 ) 2 · 2.5 D 2 0 . The

Key features of Inelastic neutron scattering experiments in YBCO-based cuprates are discussed. We underline the importance of precise oxygen content determination in samples having similar TC as well as the resolution configuration used. This may exp

We have measured the specific heat of an optimally doped superconducting ceramic Bi 2.12 Sr 1.88 CuO 6+δ between 0.2 and 8.5 K. The data obtained in a magnetic field up to 7 T allowed us to detect an anomaly at the superconducting transition ( T c
