Host Spin - Lattice Relaxation Narrowing in Pr 2 Co 3 ( N 0 3 ) 1 2 • 24 H 2 0 : M n 2 \ Gd 3 + Single Crystals
نویسنده
چکیده
Electron paramagnetic resonance of Mn2+ and Gd3+ in single crystals of Pr2Co3(N03)i2 • 24 H2O has been studied at X-band at 305 and 77 K. Mn2+ substitutes at two types of Co2 f sites whereas Gd3 substitutes at the single type of Pr3+ site in the lattice. The spin-Hamiltonian parameters have been evaluated. Observation of resolved Mn2+ and Gd3+ spectra at 305 K and their broadening on lowering the temperature are discussed in terms of host spin-lattice relaxation narrowing.

Electron Spin Resonance of Mn 2 + in Eu 2 M ” 3 ( NO 3 ) 12 · 24 H 2 O ( M ” = Zn , Co ) Single Crystals
Electron spin resonance of Mn2+ doped in Eu2M”3 (NO3)12.24H2 O (M” = Zn, Co) single crystals has been studied at 295 and 77 K using an X-band spectrometer. The observation of resolved Mn2+ spectra in Eu2Co3(NO3)12.24H2O at 295 K have been interpreted in terms of random modulation of interaction between Mn2+ and divalent cobalt ions by the rapid spin-lattice relaxation of cobalt ions. T1 of diva...

متن کاملC 1 NQR Spin - Lattice Relaxation Mechanism in Ni ( H 2 0 ) 6 SnCl 6 and Mg ( H 2 0 ) 6 SnCl 6 Crystals *
The 35C1 NQR spin-lattice relaxation mechanism in isomorphous N i(H 20 ) 6SnCl6 and M g(H20 ) 6SnCl6 crystals is reported. The spin-lattice relaxation time T1(j in the Ni compound is determined mainly by a paramagnetic relaxation. However, above ca. 400 K T1Q decreased rapidly and a log vs. T 1 curve was almost linear. This steep decrease of T1Q was explained by reorientational motions of the a...

متن کاملProbing the Electronic Structure of Y - B a - C u - O Superconductors by Copper NQR/NMR
The paper discusses some N Q R / N M R studies performed on Y B a C u O superconductors at the University of Zürich. It is shown how the resonance methods can yield information on electronic properties of quite different character. The review deals with: (1) the temperature and pressure dependence of Cu N Q R frequencies in YBa 2 Cu 4 O g (1-2-4); (2) an NQR study of the properties of Ca substi...
