Özet
The orthochromites La0.7RE0.1Ca0.2CrO3 (RE = Nd,Sm, and Eu) were prepared
by solid-state reaction and the structural, microstructural, optical, and magnetic
properties were investigated. The XRD revealed an orthorhombic perovskite
structure. The UV–visible revealed the bandgap energy values: 2.81, 2.98, and
3.12 eV for Nd, Sm, and Eu doped samples, respectively. It is explained by the
creation of the localized state. The refractive index, Urbach energy, and optical
conductivity were investigated. The magnetization investigation revealed that
the Ne´el temperature decreases with decreasing substituting ionic radius. Below
TN, all samples exhibit weak ferromagnetic behavior due to the t-e hybridization
caused by intrinsic distortions. The Nd and Sm doped samples show spin
reorientation due to the exchange interaction between the Sm3?/Nd3? and Cr3?.
The negative magnetization of the Nd-doped sample indicates its possible use as
a volatile memory device. Regarding the Eg values, our samples could be suit able candidates for optoelectronic devices
