PROBLEM TO BE SOLVED: To provide iron-rhodium magnetic powder whose magnetic properties can be controlled to develop its use by applying peculiar magnetic properties of the conventional iron-rhodium magnetic powder, and to provide a synthesis method therefor. SOLUTION: The iron-rhodium magnetic powder consists of iron and rhodium. When the iron-rhodium alloy components are expressed as Fe<SB>1-x</SB>Rh<SB>x</SB>, x is 0.4 to <0.8, and the grain sizes lie within the range of 20 nm to 200μm, and also, a reduction temperature is changed within the range from 300 to 1,200°C, so that its magnetic properties can be controlled.
