Com.utational calculations using density functional theory(DFT) were perform.d for the first tim. using the full potential linearized augm.nted plane wave plus local orbital m.thod(FP-LAPW + LO) to determ.ne the structural, elastic, electronic and m.gnetic properties of europium.based cubic perovskites EuYO_(3)(Y=Cr, m., Fe). The exchange correlation potentials of GGA along with som. analytical m.thods were adopted for the com.utation of structural and elastic properties. m.reover, the GGA + U form.0}sm.was also added for obtaining m.re precise electronic and m.gnetic properties, particularly to address the Eu-4f and Y-3d orientations in the spin-polarized double cell sym.etry. The observed lattice param.ters of these com.ounds are consistent with experim.nt. The observed bulk m.duli predict that EuCrO_(3) is harder and less com.ressible than Eum.O_(3) and EuFeO_(3). The calculated tolerance factors of these com.ounds are within the cubic sym.etry range. Our com.uted critical radius of EuCrO_(3) shows that EuCrO_(3) has a larger m.gration energy. Based on their elastic properties, these com.ounds are ductile in nature. We also com.uted the therm.l properties of these com.ounds. The band structures and density of states show that these com.ounds are m.tallic in character. The lowest ground state energy and m.gnetic m.m.nts of these com.ounds expose their ferrom.gnetic nature. The m.tallic nature and strong ferrom.gnetism.of these com.ounds m.ke them.prom.sing applicants for application in spintronic.
