中文摘要Single crystals of SrFe1-xCoxO3 solid solution with high valence ions (Fe4+/Co4+) were synthesized by combining floating-zone and high-pressure oxygen-annealing techniques. As the Co content (x) is increased, the ground state changes from the helimagnetic state (x <= 0.05) through cluster glass to the ferromagnetic state (x >= 0.2), with a high Curie temperature ranging between 245 and 337 K. We found that, within the helimagnetic state (x <= 0.05), several different magnetic phases, which possibly reflect versatile three-dimensional helical orders with multiple wave vectors, emerge depending on temperature and magnetic field strength. In addition, we observed Co-concentration-dependent systematic evolution of the complex magnetic phase diagram. Resonant soft x-ray diffraction measurements revealed a gradual decrease in the wave vector of the helix toward the ferromagnetic phase.
