The manganites Pr1 - xSrxMnO3 (x=0.5, 0.56) have been studied by means of powder neutron diffraction at high external pressures up to 4.8 GPa in Pr0.44Sr0.56MnO3 a tetragonal C-type AFM phase (TN ~125 K) is formed coexisting with the initial orthorombic A-type AFM phase (TN~220 K). In Pr0.5Sr0.5MnO3 the applications of high pressure leads to a mixture of orthorombic A-type AFM phase and tetragonal phase without long range magnetic order
Manganity PPr1 - xSrxMnO3 (x=0.5, 0.56) byly studovány neutronograficky za vysokých tlaků až 4.8 GPa. V Pr0.44Sr0.56MnO3 vzniká tetragonální AFM fáze C-typu (TN ~125 K), která koexistuje s původní orthorombickou AFM fází A-typu (TN ~220 K). V Pr0.5Sr0.5MnO3 vede použití vysokého tlaku k směsi orthorombické AFM fáze a tetragonal phase bez magnetického uspořádání na dlouhou vzdálenost
