Structural and magnetic properties of LaCrO 3 half-doped with Al

Synthesis of LnCrO3 perovskites and their color properties

“…The identification of crystalline phases through Rietveld refinement, revealed the single phase powders with orthorhombic perovskite structure according to 2104121 (LaCrO 3 ), 156319 (NdCrO 3 ), 331072 (PrCrO 3 ) ICSD database. The effectiveness of the synthesis method to obtain the perovskite is proven when we compare the results obtained in this work with others reported in the scientific literature [21][22][23][24].…”

Goodenough-Kanamori-Anderson Rules in CrI3/MoTe2/CrI3 Van der Waals Heterostructure

“…The materials corresponding to this situation include CaMnO 3 and LaCrO 3 , which are known antiferromagnets. [16][17][18][19] It can be seen from this example that Kramer's original physical picture and general rules derived in the last subsection yield consistent predictions. However, there is subtlety between the two.…”

Optimization of the Magnetocaloric Effect in Low Applied Magnetic Fields in LnOHCO3 Frameworks

“…For such optimization of MCE materials, it is becoming apparent that it is important to not just achieve a high density of magnetic cations but also to control the magnetic interactions in these compounds. It is well-established that frustrated magnetic interactions can enhance MCE behavior, including in the benchmark oxide Gd 3 Ga 5 O 12 ; − frustrated interactions enable a higher density of magnetic cations to be incorporated in a phase that remains paramagnetic to low temperature than is possible in the alternative “dilute” magnetic salts, which depend on having well separated magnetic centers to remain paramagnetic . As a result, magnetic frustration increases the maximum −Δ S m possible per unit volume or weight.…”

“…It is well-established that frustrated magnetic interactions can enhance MCE behavior, including in the benchmark oxide Gd 3 Ga 5 O 12 ; 11−13 frustrated interactions enable a higher density of magnetic cations to be incorporated in a phase that remains paramagnetic to low temperature than is possible in the alternative "dilute" magnetic salts, which depend on having well separated magnetic centers to remain paramagnetic. 14 As a result, magnetic frustration increases the maximum −ΔS m possible per unit volume or weight. It has also been shown that the Ising-like interactions in Dy 3 Ga 5 O 12 play a role in it having superior MCE performance for field changes below 2 T than found in Gd 3 Ga 5 O 12 ; 15 this concept is supported by similar improvement in the MCE properties of other families of compounds when Gd is substituted with lanthanides with Ising-like interactions.…”
