Ca₂RuO₄ has been known to have a superconducting transition under high pressure, but in recent years, a superconducting transition under normal pressure has been discovered in a thinned sample. However, its detailed structure has not been elucidated. In addition, it is necessary to clarify the appearance conditions of the superconducting phase in order to develop new superconducting materials. Here, we report on the magnetism of Ca₂RuO₄.
