The UFe4As2 system is a newly discovered iron-arsenide that contains f elements – one of only three uranium iron arsenides known to date. What is rather uncommon, is that in this material we identify that uranium contributes to magnetism at room temperature, which is not typical for this element given its small energy scales. We thus propose to further investigate this new compound in order to understand its element-specific microscopic magnetic properties and determine how the two magnetic species affect one another. According to magnetization measurements, this anisotropic material should order ferrimagnetically, confirmed by electronic band structure calculations.
