Magnetism and thermoelectricity in La0.8Sr0.2Co1−zMzO3 (M:3d transition metal)

The enhanced effect of magnetism on the thermoelectric performance of a CrI3 monolayer

“…24 Y. Fujine et al investigated the magnetic and TE properties of a La 0.8 Sc 0.2 Co 1−z M z O 3 system and found that the Seebeck coefficient is strongly correlated with the behavior of magnetization. 25 All the above studies demonstrate that magnetism has a novel effect on the TE performance.…”

Magnetically tuned thermoelectric properties of metal-oxides: a review

“…ex ( ) Due to this small energy difference in D cf and D , ex interesting spin-state transition along with different magnetic and electric phase transformations in LaCoO 3 take place with variation in the pressure, temperature, and/or different hole-substitutions. The impact of partial substitution of different metallic ions on the transport features has been reported for a variety of di/tri-valent ion replacements (Ca 2+ , Sr 2+ , Ba 2+ , Gd 3+ , Y 3+ , Mg 2+ , Al 3+ , Mn 3+/4+ , Ni 2+ , Fe 3+ ) on both at A and B sites [99][100][101][102][103][104][105][106]. These substitutions alter the spin states of the Co-ions and leads to different electrical and magnetic phase transitions within the system.…”

Synergistic effect of lattice, electronic and magnetic modulations on the thermoelectric behaviour of Cr-substituted La0.65Bi0.20Sr0.15CoO3

“…[18][19][20] The transport phenomena of LaCoO 3 have been intensively investigated for various di/tri-valent ion substitutions (Ca 2+ , Sr 2+ , Ba 2+ , Gd 3+ , Y 3+ , Mg 2+ , Al 3+ , Mn 3+ , Ni 2+ , Fe 3+ ) on both A and B sites. 19,[21][22][23][24][25] Among these, Sr 2+ substitution at the La 3+ site (i.e., La 1−x Sr x CoO 3 or LSCO) has shown spin glass insulating to ferromagnetic (FM) metallic state transition along with the thermoelectric properties at room temperature. [26][27][28][29][30] Thermoelectric efficiency of the La 1−x Sr x CoO 3 is observed to be maximum for 5% Sr substitution i.e., La 0.95 -Sr 0.05 CoO 3 , having a room temperature (RT) value of ZT ∼ 0.06.…”
