Magnetizations of spin-Peierls cuprates Cu 1- x Zn x GeO 3 with x =0, 0.005, 0.010, and 0.020 were measured in order to investigate influence of impurities on a magnetic phase. A characteristic change of the magnetization related to a phase transitio

Electron spin resonance (ESR) was investigated on the spin-Peierls system CuGeO3 and antiferromagnetic Ba2Cu3O4Cl2 at X-band and far-infrared regions (FIR). The g-values of CuGeO3 were determined to be 2.17, 2.26 and 2.11 for H∥a, H∥b and H∥c-a

We measured the magnetic-field dependence of the magnetizations of the spin-Peierls cuprates Cu 1− x Zn x GeO 3 with the x = 0, 0.005, 0.010 and 0.020. The characteristic change of the magnetization was observed and it is associated with the phase

The AC susceptibility in the cuprate compound CuGeO3, in which the spin-Peierls (SP) transition occurs around 14K in the absence of magnetic field, was measured in the magnetic field region up to 20 T to establish the magnetic phase diagram of CuGeO3

We have performed the magnetoresistance measurements of two single crystals of FeSi in the temperature range 4.2–300 K. At 4.2 K the negative magnetoresistance is observed in sample K, which has less impurities judging from its resistivity, while t

We measured the magnetization of Cu1−xMgxGeO3. A spin-Peierls-transition temperature and a critical field associated with a transition to a magnetic phase reduce up to x = 0.06. A spin-glass-like transition was not seen, although it was observed in
