Abstract:

� 2016 American Physical Society. We report the results of a muon-spin relaxation (?SR) investigation of La2-xSrxCoO4, 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?x0.6) 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 T1.5K.

Magnetic phase diagram of La2−xSrxCoO4 revised using muon-spin relaxation

Abstract:

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 .
