Magnetic skyrmions are vortex-like spin textures, which can be manipulated by external stress or pressure via magnetoelastic effects. Here, we present the observation of isostructural phase transition in a biskyrmion host hexagonal MnNiGa at around 4 GPa using pressure-dependent synchrotron x-ray powder diffraction (XRD) data analysis. Our XRD reveals anisotropic compression behavior with diffe...

A comparison is made between existing theories for self-assembling systems and experimental phase diagrams of complex systems made up of amphiphile/water/additives, with emphasis on phase transitions by changes in concentration. Evidence for di erent types of hexagonal (H) phases, in systems with detergent and lipid amphiphiles, are reviewed. It is shown that characteristics of the H phase and ...

The magnetic phase diagram of the Fe doped hexagonal ABX3 compound CsNi0.9Fe0.1Cl3 is investigated by heat capacity and magnetocaloric experiments. In spite of the high doping concentration, some phase boundaries appear surprisingly well-defined, while others are broadened significantly. The discussion of this behaviour clarifies the potentials and limitations of doping as a means to manipulate...

A monitoring device for the phase transition of polymer material with temperature variation is developed utilizing a quartz crystal resonator, and its performance has been evaluated by implementing in the melting and crystallization of polyethylene. The observation is compared with the result of DSC thermo-analysis. The experimental outcome indicates that the resonant frequency variation shows ...

In this paper, we demonstrate a novel and direct synthesis of hexagonal-shaped zinc oxide (ZnO) nanorods at very low temperature of ~ 80C simply by using metallic zinc foil and de-ionized (DI) water with few drops of ethanol. The formation of ZnO structures by the reaction of metals with DI water is suggested to occur due to the oxidation of metallic zinc in presence of water. The synthesized Z...

the mechanism by which bi-and trivalent cations affect human liver phosphatidatephosphohydrolase (pap) activity was investigated. bivalent cations up to 1 mm increased pap activity whereas at higher concentrations the activity of the enzyme decreased. the stimulatory concentration for trivalent cations such as al3+ and cr3+, however, was much lower being 2 m m and 1 m m, respectively. all catio...
