Le résumé fourni par la source
This work systematically investigates the spin glass behavior of the double perovskite Ca2FeReO6. Building on previous studies, we have developed a formula to quantify the ions distribution at B-site, incorporating the next-nearest neighbor interactions. Employing molecular field theory and Monte Carlo simulations, the influence of various arrangements of two B-site ions on frustration effects was uncovered. B-site is segmented into a and b-site, defining the number of nearest neighbors from Fea to Feb (and vice versa) as Zx(Zy). The significant frustration effects occur when 1
