XMCD studies of thin Co films on BaTiO$_3$

open access: yes, 2015
Different layer thicknesses of Cobalt ranging from 2.6 {\AA} (1.5 ML) up to 55 {\AA} (30.5 ML) deposited on ferroelectric BaTiO$_3$ have been studied regarding their magnetic behavior.

High performance millimeter-wave microstrip circulators and isolators [PDF]

open access: yes
Millimeter wave systems, phased array antennas, and high performance components all require wideband circulators (and isolators) to perform diplexing and switching, to improve isolation and Voltage Standing Wave Ratio (VSWR), and to construct IMPATT ...

Iron oxide doped boron nitride nanotubes: structural and magnetic properties

open access: yes, 2010
A first-principles formalism is employed to investigate the interaction of iron oxide (FeO) with a boron nitride (BN) nanotube. The stable structure of the FeO-nanotube has Fe atoms binding N atoms, with bond length of roughly $\sim$2.1 \AA, and binding ...

Quasi‐hexagonal nanopatterned porous cobalt ferrite thin films prepared via block copolymer self‐assembly

open access: yesNano Select
We present a novel method for fabricating dense and nanopatterned porous cobalt ferrite (CoFe2O4) thin films with a remarkable thickness of 65 nm, achieved through direct block copolymer self‐assembly.

HYSTERESIS AND ELECTRIC MODULUS ANALYSIS OF Y³⁺ DOPED MnNi-Y-TYPE HEXAGONAL FERRITE

open access: yes, 2016
The magnetic, grain morphology and dielectric properties of synthesized Sr2MnNiFe12O22 + xY2O3 (x = 0 5 wt.%) ferrite have been investigated via X-ray diffraction (XRD), scanning electron microscopy (SEM) and dielectric spectroscopy, respectively.

Characteristics of Magnetic Properties of Substituted Hexagonal Ferrites

open access: yesAdvances in Electrical and Electronic Engineering, 2006
The samples of barium hexaferrite BaFe12-2x(Me1Me2)xO19 with x from 0.0 to 0.6 were prepared by variousmethods. The cationic preference of mainly divalent Me1 = Zn, Co, Ni, Sn ions and tetravalent Me2 = Ti, Zr, Ir, Sn, Ru ionsand their combinations in substituted Ba ferrites was investigated. The substitutions were performed to reduce the grain sizeand

M-Type Barium Hexagonal Ferrite Films [PDF]

open access: yes, 2012
Magnetic garnet materials such as yttrium iron garnet (YIG) have been widely used as active components in many microwave devices.1,2,3 These devices include resonators, filters, circulators, isolators, and phase shifters. They have had a major impact on the advancement of microwave technology.

Correlation of ideal and actual shear strengths of metals with their friction properties [PDF]

open access: yes
The relation between the ideal and actual shear strengths and friction properties of clean metals in contact with clean diamond, boron nitride, silicon carbide, manganese-zinc ferrite, and the metals themselves in vacuum is discussed.
