Temperature Evolution of the Magnetism of Charge Ordered La2-xSrxCoO4 x = 0.25.
The occurrence of charge-stripe order and checkerboard charge order in La2-xSrxCoO4 has lead to a stripes versus checkerboard charge order-Neel antiferromagnet nano-phase separation debate on the origin of the hourglass shaped magnetic excitation in this material[1-3]. Resolving this dispute may prove crucial for understating the universal hourglass shaped magnetic excitation spectrum of hole doped cuprate superconductors. The key to resolving our understanding of La2-xSrxCoO4 is to resolve the structure of the charge ordered phase to lower doping levels, further away from the pure checkerboard charge order at half doping.
