Abstract: | Electron spin resonance spectra of Cu2+ doped in single crystals of strontium tartrate trihydrate grown by a diffusion technique have been investigated at 77K. Copper enters the lattice substitutionally and is trapped at two magnetically inequivalent sites. ESR measurements gave the following values for the spin-Hamiltonian parameters. Cu2+(I): ggg = 2.0380, gyy = 2.1317, gzz = 2.3918 and Axx = 26.3 G, Ayy = 56.3 G, Azz = 110.8 G. Cu2+(II): gxx = 2.0497, gyy = 2.1297, gzz = 2.3706 and Axx = 19.2 G, Ayy = 61.4 G, Azz = 107.2 G. |
