Magnetic properties, magnetocaloric effect, and critical behaviors in Co_1−xCr_xFe₂O₄

Abstract

Magnetic entropy change as a function of temperature for various Co1−xCrxFe2O4 at an applied magnetic field of 5 T.

Gallium-substituted X-type hexagonal ferrites Sr2Co2GaxFe28−xO46: effect of substitution and heating temperature on phase formation and magnetic and dielectric properties

“…Multiple broad peaks near the zero magnetic field observed for GX11–GX16 indicate multi magnetic domains and a lack of exchange coupling between the multiple phases in samples heated to 1250 °C. 47,48…”
