Proton magnetic resonance studies of TiCuH
The TiCuH structure can be described as alternating layers of TiH 2 and Cu atoms and, thus, corresponds to a two-dimensional analog of metal hydrides with CaF 2- type structures. Measurements of the proton relaxation times for TiCuH yield an activation energy of 0.79 eV for hydrogen diffusion. This...

Summary: | The TiCuH structure can be described as alternating layers of TiH
2 and Cu atoms and, thus, corresponds to a two-dimensional analog of metal hydrides with CaF
2- type structures. Measurements of the proton relaxation times for TiCuH yield an activation energy of 0.79 eV for hydrogen diffusion. This result strongly suggests the H-atoms in TiCuH jump directly between the tetrahedral sites rather than through the vacant octahedral sites as proposed for H-atom jumps in f.c.c. TiH
x. In addition, the Korringa constant and hydrogen diffusion rate for TiCuH are compared with similar parameters for TiH
x and several ternary titanium hydrides. |
