Research output: Contribution to journalArticleAcademicpeer-review


Magnetic and acoustic losses were measured in single-crystal manganese ferrites at temperatures 80 ÷ 630 K. Relaxation peaks at 230 and 540 K were observed with activation energies of 0.27 ÷ 0.42 and 0.64 ÷ 0.82 eV, respectively. Both peaks are influenced by heat-treatments resulting in different degrees of inversion and vacancy distributions.
