Refinement of the magnetic and nuclear structures in the hybrid multiferroic layered Perovskite-Like (C6H5C2H4NH3)2FeCl4 compound
(C6H5C2H4NH3)2FeIICl4 is the first example of an organic-inorganic perovskite to exhibit coupling of ferro-elasticity and ferromagnetism below TC=98K and ferro-elasticity at TC=433 K. This is shown by switching the magnetic hysteresis on and off by uniaxial pressure through the strong coupling of the magnetic and elastic domains. In this proposal we intend to refine all the different nuclear and magnetic structures reported for the title compound in order to understand the evolution of the H bridges network that produce all the series of phases transitions and how the system reaches its long range magnetic order. For that reason we apply for 1 day at D20 high flux diffractometer to perform a thermal diffractogram from 1.8 to 480 K and 1 day at D2B to collect 4 high resolution difractograms at 1.8, 300, 400 and 480K.
