    • n Yttrium (Chem) A rare metallic element of the boron-aluminium group, found in gadolinite and other rare minerals, and extracted as a dark gray powder. Symbol Y. Atomic number 39. Atomic weight, 88.9.☞ Associated with yttrium are certain rare elements, as erbium, ytterbium, samarium, etc., which are separated in a pure state with great difficulty. They are studied by means of their spark or phosphorescent spectra. Yttrium is now regarded as probably not a simple element, but as a mixture of several substances.

    • n yttrium Chemical symbol, Y; atomic weight, 89 (?). A metal, the base of the earth yttria. But little is known of this metal, and its atomic weight has never been satisfactorily determined. As obtained by Cleve, yttrium is a dark-gray powder exhibiting a metallic luster under the burnisher. It belongs, with various other rare metals, to the cerium group, in regard to most of which, from their scarcity and their resemblance to one another, but little has been definitely made out.

In news:

The concentrated light would then strike a two-layer ceramic disk known as a Neodymium and Chromium co-doped YAG (yttrium aluminum garnet) laser material.
Yttrium has often been classified as a rare earth element, though it is never found in nature as a free element.

In science:

Lee et al. reported interesting glassy behaviour in the relaxation of photo-induced conductivity in doped yttrium hydrides, Y H3−δ with δ ≈ 0.039.

We show that the linear-response formulation provides us with a qualitative as well as quantitative understanding of the spin Seebeck effect observed in a prototypical magnet, yttrium iron garnet.
Linear-response theory of spin Seebeck effect in ferromagnetic insulators
In this experiment, an ensemble of ∼ 4.5× 1016 spins in gallium-doped yttrium iron garnet was strongly coupled to the cavity mode of the CPW resonator.

Lanthanum, a heavy s-process product, shows a stepwise increase with Fe/H at [Fe/H] = -1.6, while the light s-process element yttrium varies less. ω Cen displays both cluster-like (Na –O anticorrelation) and dwa rf galaxy-like properties (low α/Fe, Eu/Fe).
Summary Talk
Yttrium and its related s2d1 transition metals Sc, La, and Lu , have a positive dTc/dp slope, as shown in Fig. 5. Lanthanum has two superconducting phases at normal pressure, dhcp at 4.8 K and fcc at 6 K .
