 Abstract: We report room temperature giant baroresistance (approximate to 128%) in Fe-49(Rh0.93Pd0.07)(51). With the application of external pressure (P) and magnetic field (H), the temperature range of giant baroresistance (approximate to 600% at 5K, 19.9 kilobars and 8 T) and magnetoresistance (approximate to -85% at 5K and 8 T) can be tuned from 5K to well above room temperature. It is shown that under external pressure, antiferromagnetic state is stabilized at room temperature and shows giant magnetoresistance (approximate to-55%). Due to coupled magnetic and lattice changes, the isothermal change in resistivity at room temperature under pressure (at constant H) as well as magnetic field (at constant P) can be scaled together to a single curve, when plotted as a function of X = T + 12.8 x H - 7.3 x P.
