Exploring Multifunctionality in Pr-Enriched LaFe12B6: Multiphysic Measurements

Pr-enriched LaFe12B6 compounds exhibit a range of magneto-related effects, including giant magnetoresistance, significant magnetostrictive, and magnetocaloric effects below 200 K using modest magnetic fields, making them promising multifunctional materials. In contrast, the parent compound LaFe12B6 requires more extreme conditions (T < 50 K and μ0H > 7 T), limiting its practical use. The ULMAG experimental setup allows for comprehensive characterization by simultaneously measuring macroscopic magnetization, resistivity, adiabatic temperature change, dilation/contraction effects, element-specific XMCD, and powder X-ray diffraction under various conditions. This characterization is ideal for unraveling the role of Pr in the interplay between magnetism and structure in the La1-xPrxFe12B6 system. Studying these magneto-structural changes and their dependence on external parameters will provide insights into the mechanisms driving these multifunctional properties.
