Magnetic phase diagram of La2−xSrxCoO4 revised using muon-spin relaxation
We report the results of a muon-spin relaxation ( μ SR ) investigation of La 2 − x Sr x CoO 4 , an antiferromagnetic insulating series which has been shown to support charge ordered and magnetic stripe phases and an hourglass magnetic excitation spectrum. We present a revised magnetic phase diagram...

| description | We report the results of a muon-spin relaxation ( μ SR ) investigation of La 2 − x Sr x CoO 4 , an antiferromagnetic insulating series which has been shown to support charge ordered and magnetic stripe phases and an hourglass magnetic excitation spectrum. We present a revised magnetic phase diagram, which shows that the suppression of the magnetic ordering temperature is highly sensitive to small concentrations of holes. Distinct behavior within an intermediate x range ( 0.2 ≤ x ≲ 0.6 ) suggests that the putative stripe ordered phase extends to lower x than previously thought. Further charge doping ( 0.67 ≤ x ≤ 0.9 ) prevents magnetic ordering for T ≳ 1.5 K . |
