PROBLEM TO BE SOLVED: To provide iron-rhodium based magnetic powder which is made to be finer particles, and of which the distribution of particle sizes and particle shapes are more uniformized. SOLUTION: The iron-rhodium based magnetic powder consisting of at least iron and rhodium as constituent elements has a content ratio x of 0.1 or more and less than 0.8 in a formula expressed by Fe1-x Rhx for the iron-rhodium alloy content, has the particle sizes of 20 nm or more and 200 μm or less, and has an intensity ratio R of 0.01 or more and 0.8 or less, when a peak intensity corresponding to the iron-rhodium alloy (110) in a X-ray diffraction spectrum is defined as IFe Rh , a peak intensity corresponding to a metal rhodium (111) as IRh , and the intensity ratio as R=IRh /(IRh+ IFe Rh ). |
