Gas Atomization Processing of LaNi5−xMm, Modified with Silicon and Tin
A high pressure gas atomization (HPGA) process has been employed to study microsegregation in LaNi4.75 Sn0.25 and LaNi4.6Si0.4 alloy powders to serve as a basis for further investigations of low cost production o...

The standard state of cerium
Based on two studies carried out about 20 years apart, it was found that the double close-packed hexagonal βCe phase slowly transformed to the face-centered cubic γCe phase at room temperature and ambient pres...

Asymmetry of the latent heat signature in b-axis oriented single crystal Gd5Si2Ge2
A 100 micron fragment of a b-axis oriented single crystal Gd5Si2Ge2 has been studied using microcalorimetry, enabling the separate measurement of the heat capacity and the latent heat. The sample was taken from t...

Do**-induced valence change in Yb5Ge4 − x (Sb, Ga) x : (x ≤ 1)
Following our earlier observation that the ytterbium valence distribution in Yb5Ge4 − x Si x was independent of x, we use 170Yb Mössbauer spectroscopy to follow ...

Synthesis, Structure, and Hydrogen-Sorption Properties of (Ti,Zr)4Ni2N x Subnitrides
We synthesize a series of new (Ti, Zr)4Ni2N0.5–1.0 subnitrides with Fe3W3C-type structure (space group Fd -3m, Z = 16, and the Pearson symbol cF112 ). Their hydrogen-sorption properties are investigated (both fro...

Open AccessNon-hysteretic first-order phase transition with large latent heat and giant low-field magnetocaloric effect
First-order magnetic transitions (FOMTs) with a large discontinuity in magnetization are highly sought in the development of advanced functional magnetic materials. Isosymmetric magnetoelastic FOMTs that do no...

Magnetocaloric Effect of Micro- and Nanoparticles of Gd5Si4
Materials exhibiting a large magnetocaloric effect (MCE) at or near room temperature are critical for solid-state refrigeration applications. The MCE is described by a change in entropy (ΔSM) and/or temperature (...
