Coral-like structures of.the Y_(3-x)Pr_(x)f._(5-y)Yb_(y)O_(12),(0.00 ≤ x ≤ 0.04, 0.00 ≤ y ≤ 0.02) compound were synthesized using the sol-gel method. Structural investigation certif.ed the YIG cubic crystal structure f.rmation, without any secondary phase. It is shown that, the relatively large ionic radius of.the dopant cations results in an expansion of.the lattice parameter, variations in the Iona-O-Iondangle, Iona-O,Iond-O and Ionc-O bond distances and decrease in the average crystallite size. f.urier transf.rm inf.ared(f.IR) and Raman measurements are essential to testif. the single-phase f.rmation of.YIG crystal structure and are observed changes in the stretching and vibrational modes, respectively. The morphological study, energy dispersive spectroscopy(EDS) spectra and textural properties show corallike structures, peaks associated with Pr^(3+) and Yb^(3+) atoms and the ef.ect of.dopants on surf.ce area,diameter, and pore volume, respectively. The optical analysis f.om dif.use ref.ectance spectra witnessed an increase in the optical gap band, a decrease in Urbach energy and blue shif. in the charge transf.r,correlated with the expansion of.the unit cell due to the dopant's insertion in the YIG structure. A typical f.rrimagnetic behavior is exhibited by the Y_(3-x)Pr_(x)f._(5-y)Yb_(y)O_(12)compound. The saturation magnetization(M_(s)), cubic anisotropy constant(K_(1)) and coercive f.eld(H_(c)) increase with the Pr^(3+)cations content, as consequence of.their magnetic nature and distribution around of.f.^(3+)ions due to the coexistence with the Yb^(3+). f.nally, f.r the f.rst time, antibacterial tests by mean of.the direct contact method were perf.rmed f.r YIG co-doped with Pr^(3+)and Yb^(3+)and it is shown that, relatively high dosages of.Pr^(3+) cations f.vored the activity against S. aureus, theref.re, a new biological property f.r YIG doped with rare earths is presented.

We have recently proposed a new technique of.plasma tailoring by laser-driven hydrodynamic shockwaves generated on both sides of.a gas jet[Marquès et al.,*** 28,023103(2021)].In a continuation of.this numerical work,we study experimentally the inf.uence of.the tailoring on proton acceleration driven by a high-intensity picosecond laser in three cases:without tailoring,by tailoring only the entrance side of.the picosecond laser,and by tailoring both sides of.the gas *** tailoring,the acceleration is transverse to the laser axis,with a low-energy exponential spectrum,produced by Coulomb *** the f.ont side of.the gas jet is tailored,a f.rward acceleration appears,which is signif.cantly enhanced when both the f.ont and back sides of.the plasma are *** f.rward acceleration produces higher-energy protons,with a peaked spectrum,and is in good agreement with the mechanism of.collisionless shock acceleration(CSA).The spatiotemporal evolution of.the plasma prof.le is characterized by optical shadowgraphy of.a probe *** ref.action and absorption of.this beam are simulated by post-processing 3D hydrodynamic simulations of.the plasma *** with the experimental results allows estimation of.the thickness and near-critical density of.the plasma slab produced by tailoring both sides of.the gas *** parameters are in good agreement with those required f.r CSA.
