AbstractCrystals of EuPO4, EuAsO4, and EuSbO4 were grown by chemical vapor transport. These compounds exhibit complex anions and they crystallize in different structures. The modelling of the chemical transport experiment was carried out with the program TRAGMIN.

Mössbauer studies of 151Eu in europium oxalate, europium bissalen ammonium and europium benzoate
Hyperfine Interactions, 2006Although a number of europium water insoluble chelates have been prepared for several decades, the covalent nature of these compounds has never been established in any quantitative fashion. Shifts in the I.R. bands and conductivity measurements of these salts were hitherto used to qualitatively compare their molecular nature. In this communique we have

The first fully structurally characterized ternary europium palladium hydrides (deuterides) are reported. The most Eu rich compound is Eu(2)PdD(4). Its beta-K(2)SO(4) type structure (space group Pnma, a = 749.47(1) pm, b = 543.34(1) pm, c = 947.91(1) pm, Z = 4) contains tetrahedral 18-electron [PdD(4)](4)(-) complex anions and divalent Eu cations.

We report here the observation, for the first time, of the enhancement of Europium-Tetracycline complex emission in cholesterol solutions. This enhancement was initially observed with the addition of the enzyme cholesterol oxidase, which produces H(2)O(2), the agent driver of the Europium tetracycline complex, to the solution.

Mössbauer Measurements in Europium-Calcium and Europium-Strontium Alloys
Journal of Applied Physics, 1970Mössbauer effect measurements have been performed for EuxCa1−x and EuxCa1−x (0≤x≤1) alloys using the 22-keV γ-line in 151Eu. The hyperfine (hf) fields extrapolated to zero europium content are −110 kOe for the EuCa system and −140 kOe for the CuSr system as compared to −150 kOe for the EuBa and EuYb system.

The relaxation rate of europium in europium iron garnet
Journal of Magnetism and Magnetic Materials, 1976Abstract The relaxation rate of europium ions in europium iron garnet (EulG) was estimated by assuming that the crystal field is modulated by optical phonons. Mixing J = 2 states into the J = 0 and J = 1 states by the static rhombic fields breaks the “triangle selection rule” and makes possible this mechanism.
