Description
Polarized neutron-diffraction experiments have been performed in search of the orbital magnetic moments recently predicted in a theory for the cuprate metals. Both La2-xSrxCuO4 [LSCO(x)] and YBa2Cu3O6+x [YBCO(x)] compounds were investigated. No definitive evidence for the existence of such a three-dimensionally ordered moment was found in any of these samples within experimental uncertainty, which was as low as 0.01μB. We have also investigated the possibility that a magnetic rod exists parallel to the c axis in the case of two- or quasi-two-dimensional ordering in the (a,b) plane and have set an upper limit for the total moment to be 0.1μB in LSCO (x=0.1). copyright 1999 The American Physical Society
