coral-like structures of th. y.(3-x)Pr_(x)Fe_(5-y.y._(y.O_(12),(0.00 ≤ x ≤ 0.04, 0.00 ≤ y.≤ 0.02) compound were sy.th.sized using th. sol-gel meth.d. Structural investigation certified th. y.G cubic cry.tal structure formation, with.ut any.secondary.ph.se. It is sh.wn th.t, th. relatively.large ionic radius of th. dopant cations results in an expansion of th. lattice parameter, variations in th. Iona-O-Iondangle, Iona-O,Iond-O and Ionc-O bond distances and decrease in th. average cry.tallite size. Fourier transform infrared(FTIR) and Raman measurements are essential to testify.th. single-ph.se formation of y.G cry.tal structure and are observed ch.nges in th. stretch.ng and vibrational modes, respectively. Th. morph.logical study. energy.dispersive spectroscopy.EDS) spectra and textural properties sh.w corallike structures, peaks associated with.Pr^(3+) and y.^(3+) atoms and th. effect of dopants on surface area,diameter, and pore volume, respectively. Th. optical analy.is from diffuse reflectance spectra witnessed an increase in th. optical gap band, a decrease in Urbach.energy.and blue sh.ft in th. ch.rge transfer,correlated with.th. expansion of th. unit cell due to th. dopant's insertion in th. y.G structure. A ty.ical ferrimagnetic beh.vior is exh.bited by.th. y.(3-x)Pr_(x)Fe_(5-y.y._(y.O_(12)compound. Th. saturation magnetization(M_(s)), cubic anisotropy.constant(K_(1)) and coercive field(h.(c)) increase with.th. Pr^(3+)cations content, as consequence of th.ir magnetic nature and distribution around of Fe^(3+)ions due to th. coexistence with.th. y.^(3+). Finally. for th. first time, antibacterial tests by.mean of th. direct contact meth.d were performed for y.G co-doped with.Pr^(3+)and y.^(3+)and it is sh.wn th.t, relatively.h.gh.dosages of Pr^(3+) cations favored th. activity.against S. aureus, th.refore, a new biological property.for y.G doped with.rare earth. is presented.
