Abstract

Abstract: We report on the result of muon spin relaxation measurements in a deuterated specimen of cobalt oxyhydrate superconductor, , which exhibits a hysteresis resembling ferromagnetic order in magnetic susceptibility. While the possibility of bulk ferromagnetic order is eliminated by the absence of spontaneous muon precession signal under zero field, the spectra indicate the appearance of magnetic domains below in accordance with a hysteresis in the susceptibility. This correlation demonstrates strong coupling between the water layers and the electronic state of CoO2 layers. [Copyright &y& Elsevier]
