We observed the temperature and the x -dependence of the 139 La-NQR spectra in magnetically ordered La 2- x Ba x CuO 4 . The internal field at La nuclei increases discontinuously at T c * , where the nuclear relaxation rate is enhanced and shows its

The nuclear magnetic resonance (NMR) of 139 La in La 2− x M x CuO 4 (M=Ba, Sr) is investigated for x=0.012. The internal field at the La site increases abruptly at the successive magnetic transition temperature in both LaBa and LaSr systems.

Low temperature heat capacity was measured as a function of x in Pr 2−x Ce x CuO 4 . The temperature linear term, γT, increases linearly, and the Debye temperature decreases with x. The Einstein contribution to the heat capacity is large and decre

Measurements of electron spin resonance and magnetization have been performed on the cubic B-20 Fe x Co 1- x Si (0.3≤ x ≤0.85). The magnetization process on Fe 0.8 Co 0.2 Si indicates that this sample is a helimagnet with the cone-ferro-magnetic

Nuclear quadrupole resonance (NQR) of 139 La in La 2- x Ba x CuO 4 has revealed an unexpected enhancement of nuclear relaxation rates, 1/ T 1 and 1/ T 2 , with Ba-doping in the low-temperature region, suggesting the occurrence of magnetic instability
