Magnetostructural irreversibilities inR5Ge3(R= Gd, Nd) intermetallics

Magnetic properties of Gd intermetallics

Using first-principles calculations, based on disordered local moment theory, combined with the selfinteraction corrected local spin density approximation, we study magnetic interactions in GdX intermetallics for X = Cu, Zn, Ga, Cd, and Mg. Our predicted magnetic orders and ordering temperatures both at zero and other pressures agree well with experiments including the large increase in the Cur...

Hyperfine anomalies in Gd and Nd

The hyperfine anomalies in Gd and Nd have been extracted from the experimental hyperfine structure constants using a new method. In addition to the values of the hyperfine anomaly new improved values of the nuclear magnetic dipole moment ratios are derived. PACS Numbers: 21.10.Ky, 31.30.Gs, 32.10.Fn

MgCuAl2-type Intermetallics REPdCd2(RE = Ce, Pr, Nd, Sm)

The cadmium-rich intermetallic compounds REPdCd2 (RE = Ce, Pr, Nd, Sm) were obtained by high-frequency melting of the elements in sealed niobium ampoules and subsequent annealing in muffle furnaces. The REPdCd2 phases crystallize with the orthorhombic MgCuAl2-type structure, space group Cmcm. The structure of NdPdCd2 was refined from single-crystal X-ray diffractometer data: a = 421.9(3), b = 9...

Unveiling the (De)coupling of magnetostructural transition nature in magnetocaloric R5Si2Ge2 (R5Tb, Gd) materials

Low threshold monocrystalline Nd:(Gd, Lu)2O3 channel waveguide laser.

We report the first waveguide laser based on a rare-earth-doped sesquioxide. A 2 microm thick lattice matched Nd(0.5%):(Gd, Lu)(2)O(3) film with a nearly atomically flat surface has been epitaxially grown on a Y(2)O(3) substrate, using pulsed laser deposition. The film has been structured with reactive ion etching and a rib channel waveguide laser has been realized. Laser radiation at 1075 nm a...
