Metal-insulator transition in Ti-substituted Ca1.78Sr0.22RuO4
The phase diagram of Ca2-xSrxRuO4 shows a metal insulator transition at low Sr concentration (x<0.2) and a metamagnetic transition due to the competition of various magnetic instabilities at slightly higher Sr content (0.2<x<0.6). We recently found that Ti substitution in this latter concentration range induces a metal-insulator transition to occur as function of temperature, whose magnetic and structural properties are proposed here to be studied by four-circle neutron diffraction.
