Revealing the Magnetic Structure and Properties of Mn(Co,Ge).

The atomic and magnetic structures of Mn(Co,Ge) are reported herein. The system crystallizes in the space group 6/ as a superstructure of the MgZn-type structure. The system exhibits two magnetic transitions with associated magnetic structures, a ferromagnetic (FM) structure around room temperature, and an incommensurate structure at lower temperatures.

Influence of nano-VC on the structural and magnetic properties of MnAlC-alloy.

Alloys of MnAlC with additions of VC nano-particles have been synthesized and their properties evaluated. The MnAlC(VC) (x = 0.25, 0.

Field induced crossover in critical behaviour and direct measurement of the magnetocaloric properties of LaPrCaSrMnO.

LaPrCaSrMnO has been investigated as a potential candidate for room temperature magnetic refrigeration. Results from X-ray powder diffraction reveal an orthorhombic structure with Pnma space group. The electronic and chemical properties have been confirmed by X-ray photoelectron spectroscopy and ion-beam analysis.

Structural, microstructural and magnetic evolution in cryo milled carbon doped MnAl.

The low cost, rare earth free τ-phase of MnAl has high potential to partially replace bonded NdFeB rare earth permanent magnets. However, the τ-phase is metastable and it is experimentally difficult to obtain powders suitable for the permanent magnet alignment process, which requires the fine powders to have an appropriate microstructure and high τ-phase purity. In this work, a new method to make high purity τ-phase fine powders is presented.

Influence of Cobalt Substitution on the Magnetic Properties of FePB.

The substitutional effects of cobalt in (FeCo)PB have been studied with respect to crystalline structure and chemical order with X-ray diffraction and Mössbauer spectroscopy. The magnetic properties have been determined from magnetic measurements, and density functional theory calculations have been performed for the magnetic properties of both the end compounds, as well as the chemically disordered intermediate compounds. The crystal structure of (FeCo)PB is tetragonal (space group I4/mcm) with two different metal sites, with a preference for cobalt atoms in the M(2) position (4c) at higher cobalt contents.

[Aquagenic pruritus from polycythaemia vera--treatment with paroxetine, a selective serotonin reuptake inhibitor].

Pruritus is one of the most frequent and bothersome symptoms of polycythaemia vera and other chronic myeloproliferative disorders. The treatment is often difficult and ineffective. Here, we present four patients with severe pruritus, three of whom were successfully treated with paroxetin, a selective serotonin reuptake inhibitor.
