Low damping magnetic properties and perpendicular magnetic anisotropy in the Heusler alloy Fe1.5CoGe

AIP Advances, 2019
We present a study of the dynamic magnetic properties of TiN-buffered epitaxial thin films of the Heusler alloy Fe1.5CoGe. Thickness series annealed at different temperatures are prepared and the magnetic damping is measured, a lowest value of α = 2.18 ×

Ferrimagnetism and antiferromagnetism in half-metallic Heusler alloys

, 2007
Half-metallic Heusler alloys are among the most promising materials for future applications in spintronic devices. Although most Heusler alloys are ferromagnets, ferrimagnetic or antiferromagnetic (also called fully-compensated ferrimagnetic) alloys ...

Fermi Surface Structure Revealed by Quantum Oscillations in Half‐Heusler Semimetal LuAuSn

Rare Metals, EarlyView.
ABSTRACT The Fermi surface structure in the half‐Heusler semimetallic compound LuAuSn was systematically investigated using quantum oscillation studies of high‐quality single crystals and first‐principles calculations. Clear bulk quantum oscillation signals were observed for multiple complementary physical properties, including magnetization, Hall ...

Resistivity and Thermopower of Ni2.19Mn0.81Ga

, 2004
In this paper, we report results of the first studies on the thermoelectric power (TEP) of the magnetic heusler alloy Ni$_{2.19}$Mn$_{0.81}$Ga. We explain the observed temperature dependence of the TEP in terms of the crystal field (CF) splitting and ...

High Power Density for All‐Fe2VAl‐based Thermoelectric Module by Enhancing the Power Factor of p‐type Leg Through Defect‐Engineering and Wetting Effect

Small Methods, EarlyView.
ABSTRACT The high thermoelectric performance of Fe2VAl stems from its sharply rising band edges on either side of the band gap, which is highly sensitive to composition. Addressing reproducibility and scale‐up challenges, we have developed a strategy to enhance its p‐type thermoelectric performance by defects and grain boundary engineering through ...

The Heusler-type alloy MgZn₂Ce

Acta Crystallographica Section E Structure Reports Online, 2007
Single crystals of the MgZn2Ce alloy (magnesium dizinc cerium) were synthesized by a two-step method which couples the thermal treatment of pressed pellets of the pure elements with subsequent arc melting. The compound crystallizes in a Heusler-type (MnCu2Al) structure in the space group Fm\overline{3}m, with one Zn site (site symmetry \overline{4}3m),
