Jump Frequency of Cd Tracer Atoms in β-Mn
نویسندگان
چکیده
The jump frequency of Cd tracer atoms in pure and Al-doped β-Mn was determined from measurements of quadrupole relaxation using the method of perturbed angular correlation of gamma rays. The jump frequency of Cd in β-Mn containing about 4.5 at.% Al had an activation enthalpy of 0.67(3) eV. In pure β-Mn at 950 K, the jump frequency was a factor about 8 larger than the value of 9.2 MHz in the alloy. Information was also obtained about the sluggish kinetics of the α-Mn to β-Mn polymorphic transformation.

Jump frequencies of Cd tracer atoms in L12 lanthanide gallides
Jump frequencies of Cd tracer atoms were measured in three lanthanide gallides having the L12 structure: DyGa3, ErGa3 and LuGa3. In/Cd impurity probe atoms were observed to occupy the non-cubic Ga-sites through the nuclear quadrupole interaction using the method of perturbed angular correlation of gamma rays (PAC). Measurements at elevated temperatures exhibited nuclear relaxation (damping) of ...
متن کاملDiffusion in Intermetallic Compounds Studied Using Nuclear Quadrupole Relaxation
The jump frequency of Cd tracer atoms was measured as a function of temperature in seven rare-earth tri-indide intermetallic compounds having the L12, or Cu3Au, structure. The frequency, proportional to the diffusivity, was detected by relaxation of nuclear quadrupole interaction at Cd nuclei caused by reorientation of the electric field gradient in each diffusive jump. Measurements were made u...
متن کاملAtom movement in In3La studied via nuclear quadrupole relaxation.
Jump frequencies of Cd tracer atoms in In3La were measured via nuclear quadrupole relaxation caused by stochastic reorientation of the electric field gradient using the method of perturbed angular correlation of gamma rays. Activation enthalpies of 0.53(1) and 0.81(1) eV were found at the two phase boundaries, which differ in composition by only about 0.1 at. %. The jump frequency was found to ...
متن کاملIsotope Effect in Diffusion
A derivation of the classical jump rate I' for tracer diffusion aimed at a clear expression for the mass dependence of the frequency factor v is presented. The derivation is effected without using the usual collective normal coordinates which usually combine the masses in a complicated way. v depends explicitly on the mass of the surrounding host atoms (as well as on the tracer-atom mass) if th...
متن کاملSynthesis, spectroscopic investigation and coductometry of a new hexadentate symmetric Schiff base ligand containing N2O2S2 donor atoms and related complexes with Cd(II), Zn(II), Co(II) and Mn (II) metal ions
In this paper, we report the synthesis and characterization of a new symmetric macroacyclic Schiff base ligand (H2L) and related complexes with different metals. (H2L) was synthesized by the one pot condensation reaction of 2-[2-(2-formyl phenoxy)ethoxy]benzaldehyde and 2-aminobenzenethiol in a 1:2 molar ratio. The acyclic Schiff base was characterized by IR, NMR spectroscopy and elemental anal...
