Field-controlled phase separation at the impurity-induced magnetic ordering in the spin-Peierls magnet CuGeO3

V. N. Glazkov, A. I. Smirnov, H. -A. Krug von Nidda +3

The fraction of the paramagnetic phase surviving at the impurity-induced antiferromagnetic order transition of the doped spin-Peierls magnet Cu(1-x)Mg(x)GeO3 (x < 5%) is found to i…
