RESULTS The magnetic and other properties of these materials are largely determined by the intercalate ion and differences between the niobium and tantalum compounds, of otherwise similar composition, are small, with the exception of the iron intercalates.

The nuclear magnetic moment of 181 Ta is measured by NMR of a tantalum solution. For tantalum dissolved in HF/HNO 3 broad lines arising from 181 Ta nuclei in TaF 6 − complexes are observed at room temperature. A study of linewidth vs temperature shows motional narrowing of the quadrupole broadened line with increasing temperature.

Tantalum pentoxide (Ta 2 O 5), one of tantalum's compounds, is a dielectric material and is used to make capacitors. It is also used to make a glass with a high index of refraction that is used in camera lenses. A composite consisting of tantalum carbide (TaC) and graphite is one of the hardest materials known and is used on the cutting edges ...

The Hall coefficient in the ferromagnetic intercalates varies linearly with the magnetic susceptibility for temperatures above the Curie temperature, Tc, and as the square of the resistivity for temperatures below Tc. We have observed that the Hall coefficient of Fe 1/3 TaS 2 varies non-linearly with the applied field near the Curie …

Giovanni Baccolo relates tales of tantalum, an element known, and named, for its inertness, yet one that holds some surprises, such as a naturally occurring nuclear isomer.

The physical properties of niobium, tantalum, molybdenum and tungsten are reviewed in relation to the properties of the other elements of groups IVa, Va and VIa of the periodic table. Zone-refined specimens of niobium and tantalum have been prepared and resistivity, magnetic susceptibility and thermal e.m.f. measurements made in the temperature ...

Spin transport in tantalum studied using magnetic single and double layers

Before we explore tantalum's magnetic properties, let's first examine some of its key characteristics: Density: Tantalum is a dense metal, with a density of approximately 16.6 grams per cubic centimeter (g/cm³). Its high density gives it substantial weight and makes it suitable for applications where durability and strength are essential.

Magnetic material from step 1 was reprocessed and cleaned on a second separator at 0.72 Wb/m². The non-magnetic material from steps 1 and 2 was reprocessed to clean the cassiterite and recover fugitive tantalum. The magnetic tantalum concentrates recovered from each of the three steps were combined into a final tantalum product.

Tantalum oxide thin films are deposited by DC reactive magnetron sputtering from a tantalum metallic target and argon + oxygen.

This finding correlates well with previous assessment of the negligible ferromagnetism of tantalum implants 47, 48. This conclusion applies to 7.0T MR as well as to 1.5 and 3.0T MR, given that the strongest magnetic B 0 gradient is similar for these instruments. This finding adds to the literature given that, to the best of our knowledge, …

Tantalum is a chemical element with symbol Ta and atomic number 73. Previously known as tantalium, its name comes from Tantalus, an antihero from Greek mythology. Tantalum is a rare, hard, blue-gray, lustrous Transition Metal that is highly corrosion-resistant. It belongs to group 5 of the periodic table having trivial name null.

Tantalum — a rare, blue-gray, very hard transition metal — was discovered in 1801 or 1802. However, extensive use of the metal did not begin until 1940, when it became an important material for capacitors used in electronics. Tantalum is almost always found with niobium. Although it is a metal, tantalum is not found in metallic form in nature.
