We present low-temperature volume thermal expansion, beta, and specific heat, C, measurements on high-quality single crystals of CeNi2Ge2 YbRh2(Si0.95Ge0.05)(2) which are located very near to quantum critical points. For both systems, beta shows a more singular temperature dependence than thus the Grüneisen ratio Gamma proportional beta/C diverges as T-->0. CeNi2Ge2, our results in accordance with spin-density wave (SDW) scenario for three-dimensional spin fluctuations. By contrast, observed...

Structural, magnetic, and magnetocaloric properties of the MnFe(P,Ge) compounds were systematically studied on both bulk alloys melt-spun ribbons. The experimental results show that critical behavior phase transition can be controlled by changing either compositions or annealing conditions. thermal hysteresis is found to tunable. It reach very small values, while maintaining a large effect in range working temperatures under field changes may produced conventional permanent magnets....

Mn Fe P 1 − x Si compounds with x=0.10,0.20,0.24,0.28,…,0.80,1 were prepared by high-energy ball milling and solid-state reaction. The structural, magnetic, magnetocaloric properties are investigated as a function of temperature magnetic field. X-ray diffraction studies show that the samples in range from x=0.28 to 0.64 adopt hexagonal Fe2P-type structure small amount second phase which increases increasing content. lower content orthorhombic Co2P-type structure. Magnetic measurements...

Whether SmB${}_{6}$ is a true Kondo insulator has been 40-year-old puzzle, as its unexpected finite low-temperature electric conductance defies that simple stereotyping. Using angle-resolved photoelectron spectroscopy, scientists find an important piece of the puzzle in material's electronic band structure, including signature topological surface conducting states.

We have studied the magnetocaloric effect in MnFe(P,Si,Ge) compounds. The structural properties of compounds were determined by x-ray diffraction. homogeneity and stoichiometry checked electron probe microanalysis. Curie temperature is found to be near room temperature. Specific-heat measurements made on these show a first-order ferromagnetic—paramagnetic phase transition. derived from magnetization data shows that this as large Gd-based MnFeP1−xAsx This means we succeeded totally replacing...
