Supporting data: "Magnetic phase diagram of La_{2-x}Sr_{x}CoO_{4} revised using muon-spin relaxation" Open Access

Abstract form the article: We report the results of a muon-spin relaxation (μSR) 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≳1.5K.
