Using the experimental capability of novel X-ray diffraction instrument available at 25 Tesla Florida Split Coil Magnet NHMFL, Tallahassee we present an extensive investigation on magnetostriction polycrystalline AlFe2B2. The was measured near ferromagnetic transition temperature (Curie TC = 280 K, determined via DC magnetization measurements), namely, 250, 290, and 300 K. AlFe2B2 exhibits anis...
