Search for magnetic ordered phase in Zn0.99Co0.01O compound using μSR method

Abstract

The behavior of the polarization of negative muons in Zn 0.99 Co 0.01 O was studied in order to search for a possible magnetic ordered phase. The sample was obtained using solid phase synthesis from ZnO and Co 3 O 4. Measurements were performed in a magnetic field of 1.5 kG transverse to the muon spin in a temper ature range of 5-300 K and in the absence of an external magnetic field at 6 K. No evidence of long range magnetic order were observed.
