Abstract
The structural, heat capacity, and magnetic properties of Y2Mo2(1-x)Ti2xO7 were investigated in this work. Y2Mo2(1-x)Ti2xO7 maintains the pyrochlore structure, but lattice constants are observed to decrease continuously with the Ti4+ doping. The magnetic measurements indicate a magnetic phase transition at low temperature for all Ti-doped samples, and the Ti4+ doping suppresses the transition temperature. This is ascribed to the diluted effect of nonmagnetic Ti4+ substitution of magnetic Mo4+. The heat capacity data confirm that the low-temperature magnetic phase is spin glass in the Ti4+-doped Y2Mo2(1-x)Ti2xO7 system. The M(H) data reveals the coexistence of antiferromagnetic and ferromagnetic interactions at low temperatures.
