Electron Spin Resonance of Ni-doped CuGeO${}_3$ in the paramagnetic, spin-Peierls and antiferromagnetic states: Comparison with non-magnetic impurities

B. Grenier, P. Monod, M. Hagiwara +7

We have performed Electron Spin Resonance measurements on single crystals of the doped spin-Peierls compounds CuGe${}_{1-y}$Si${}_y$O${}_3$ and Cu${}_{1-x}$M${}_x$GeO${}_3$ with M = Zn, Mg, Ni…
