“…All of the samples show hysteretic behavior with linear components, features of an AFM material, in accordance with that reported for BLFO samples . When compared to the results for the sample of pure BFO found by Dias et al., an increasing magnetization is observed . The substitution of La maybe affects the magnetic properties, which further produces distortion in the unit cell due to the difference in ionic radii of host and dopant atoms.…”

Optimizing Structural, Optical, Dielectric, and Magnetic Properties of (Bi_1–xLa_x)FeO₃ (0.00 ≤ x ≤ 0.06) Sintered Ceramics

(Bi1–x La x )FeO3 (0.00 ≤ x ≤ 0.06) ceramics have been synthesized through a mixed oxide route to investigate their structural, morphological, optical, dielectric, and magnetic properties. All the samples are revealed to be in rhombohedral structures along with the R3c space group and 161 space group number. A high relative permittivity and the lowest tangent loss are observed in BLFO samples at the frequency range 1–100 MHz. The optical studies show that the excitation energy increases with the increasing La content. Moreover, the magnetization being strongly affected by crystallite size and microstrain has been investigated. The band gap energy increases with the increasing La content. The overall result of pure and doped La contents in BFO ceramics shows enhanced structural, dielectric, and optical properties.

“…This approach was further extended to the synthesis of other magnetic as well as catalytic materials. There are reports in the literature on magnetic materials being prepared by cryomilling in the nanocrystalline form, such as NiCrAlY [252], NiCoCrAlYSi [163,253] MnBi [254], τ-MnAlC [255,256], MnAlC/α-Fe [257], Carbon doped MnAl [258], Cobalt ferrite [259],γ-Fe 4 N [260], BiFeO 3 [261].

The milling of materials at cryogenic temperature has gained importance both in academic as well as the industrial community in the last two decades, primarily because of significant advantages this technique as compared to milling at room temperature; environmental friendly nature, cost-effectiveness, rapid grain refinement, less contamination, and large scale production capability of various nanomaterials. Scientifically, milling at cryo-temperature exhibits several distinct material related phenomena; suppression of recovery and recrystallization, predominant fractures over cold welding, significantly low oxidation, and contamination, leading to rapid grain refinement. Cryomilling has extensively been used to obtain finer scale powder of spices for the preservation of aroma, medicines for effective dissolution, or amorphization. It has been considered an environmentally friendly process as it utilizes benign liquid nitrogen or argon without discharging any toxic entity to the environment, making the process attractive and sustainable. The present review is intended to provide various scientific as well as technological aspects of cryomilling, environmental impact, and future direction.
