Abstract:
We report on the synthesis conductions and results of experimental investigations of the crystal structure and magnetic properties of a new magnetic compound YbFeTi$_{2}$O$_{7}$. According to the X-ray diffractometry data, the crystal structure of the investigated compound is described by the rhombic space group $Pcnb$ with unit cell parameters of $a$ = 9.8115(1) $\mathring{\mathrm{A}}$, $b$ = 13.5106(2) $\mathring{\mathrm{A}}$, and $c$ = 7.31302(9) $\mathring{\mathrm{A}}$ and atomic disordering in the distribution of iron ions Fe$^{3+}$ over five structural sites. The magnetic measurements in the lowtemperature region revealed a kink in the temperature dependence of the magnetic moment and its dependence on the sample magnetic prehistory. The experimental results obtained suggest that with a decrease in temperature the sample passes from the paramagnetic state to the spin-glass-like magnetic state characterized by a freezing temperature of $T_f$ = 4.5 K at the preferred antiferromagnetic exchange coupling in the sample spin system. The chemical pressure variation upon replacement of rare-earth ion $R$ by Yb in the $R$FeTi$_2$O$_7$ system does not change the crystal lattice symmetry and magnetic state.
