<p>A series of MBa<sub>2</sub>Cu<sub>3-x</sub>CrxO<sub>7-y</sub> (M = Y; La; Nd; Sm and Yb; <em>x </em>= 0, 0.05, 0.15, 0.25) materials were synthesized in air by self-propagating high-temperature synthesis (SHS) involving reaction of stoichiometric mixtures of rare-earth metal (III) oxide, barium peroxide, copper metal, chromium (III) oxide and sodium perchlorate. All the SHS processes were followed by sintering in oxygen at 950 °C for 2h. The products were characterized by SEM, X-ray powder diffraction, UV, superconductive transition temperatures (T<sub>c</sub>) and magnetic susceptibility (χ) measurements. X-ray diffraction data showed that single phase orthorhombic (or tetragonal for M = Nd) materials were produced. All series of materials showed a systematic increase in lattice parameters and unit cell volume with chromium content (M = Y: <em>x </em>= 0, <em>V </em>= 174.25 Å3; <em>x </em>= 0.25, <em>V </em>= 175.10 Å3). Thermal stability of all the SHS prepared materials increased with <em>x</em>. Oxygen content of all the samples increased with <em>x</em>, but did not exceed 7.0. Superconductivity transition temperature decreased with chromium substitution in all systems (98-77 K). Magnetic susceptibility decreased with chromium substitution.</p>
