Likodimos %A Niarchos, N. %A Psyharis, B. %X Electron paramagnetic resonance obtained from the tetragonal RBa2Cu3O6+x (R ≡ Nd, Sm, Tm) compounds exhibit a well defined line resulting from coupled divalent Cu ions. Below 20 K the g parameter of this signal is strongly temperature dependent. At about the same temperatures there is a ferromagnetic-like transition in the magnetic susceptibility. © 1992 Taylor & Francis Ltd. %B Philosophical Magazine B: Physics of Condensed Matter; Statistical Mechanics, Electronic, Optical and Magnetic Properties %V 65 %P 1381-1387 %G eng %U https://www.scopus.com/inward/record.uri?eid=2-s2.0-84910921732&doi=10.1080%2f13642819208215105&partnerID=40&md5=f35c076928461ca8f6f1d39fc32ec3ca %R 10.1080/13642819208215105
