MAGNETIC ORDER OF THE CU PLANES AND CHAINS IN RBA2CU3O6+X
Polarized and unpolarized neutron-diffraction measurements have been taken to determine the magnetic structure of the Cu spins in the RBa2Cu306+"system as a function of temperature.Most of the results have been obtained on two (semiconducting) oxygen-deficient single crystals of composition NdBa2Cu306& and NdBa2Cu30635...
