Renormalized field theory for the static crossover in dipolar ferromagnets [PDF]
, 1988 A field theoretical description for the static crossover in dipolar ferromagnets is presented. New non leading critical exponents for the longitudinal static susceptibility are identified and the existence and magnitude of the dip in the effective ...

Ga-, Y-, and Sc-substituted M-type ferrites for self-biasing circulators in LTCC microwave modules
AIP Advances, 2020 The partial substitution of Fe3+ by diamagnetic Me3+ in BaMexFe12-xO19 with Me = Ga and Y (0 ≤ x ≤ 2) was studied. Samples were synthesized by the mixed-oxide route and their properties were compared to BaScxFe12-xO19 ferrites.

Magneto-Electric Effects on Sr Z-type Hexaferrite at Room Temperature
, 2011 In this paper, magnetoelectric effects of Sr Z-type hexaferrite, Sr3Fe24Co2O41, at room temperature is measured. The change in remanence magnetization was measured by applying a DC voltage or electric field across a slab of hexaferrite.

Critical dynamics of ferromagnets [PDF]
, 1988 The crossover in the dynamics from isotropic to dipolar critical behaviour has been a matter of debate over many years. We review a mode coupling theory for dipolar ferromagnets which gives a unified explanation of the seemingly contradictory ...
