Electronic Magnetic and Thermoelectric Properties of Spinel Ferrite Systems

This book explores magnetic properties and critical temperatures in inverse ferrite Fe������(M������Fe������)O��� spinels (e.g. Fe Co Ni). It calculates transition and Curie Weiss temperatures providing insights into their thermodynamic behavior. Using the full potential linearized augmented plane wave (FP-LAPW) method it investigates electrical and magnetic structures of spinel chromite revealing magnetic moments in MnCr���S���. Seebeck coefficient and electrical conductivity are also calculated. Advanced techniques like Monte Carlo DFT+U and FLAPW analyze magnetic characteristics of LiMn���.���Ni���.���O��� and electronic/magnetic structures of Fe���O���. High-temperature series expansions calculate N��el temperature and critical exponents while GFT determines thermal magnetization and susceptibility. The analysis exposes exchange interactions' effects on magnetic order and introduces asymmetric phases in ferrimagnetic spinel systems. This book serves as an invaluable resource for researchers academics and enthusiasts seeking a comprehensive understanding of magnetic properties and critical phenomena within diverse spinel materials.
